Basic Metallurgy of Cast Iron

The term ‘cast iron’, like the term ‘steel’, identifies a large family of ferrous alloys. Cast irons primarily are alloys of iron that contain more than 2% carbon and form from 1 to 3% silicon. Wide variations in properties can be achieved by varying the balance between carbon and silicon, by alloying with various metallic or nonmetallic elements, and by varying melting, casting and heat treating practices.

Cast irons, as the name implies, are intended to be cast to shape rather than formed in the solid state. Cast irons have low melting temperatures, are very fluid when molten, do not form undesirable surface films when poured, and undergo slight to moderate shrinkage during solidification and cooling. However, cast irons have relatively low impact resistance and ductility, which may limit their use.

Mechanical properties of cast irons - especially strength, ductility, and modulus of elasticity - depend strongly on structure and distribution of microstructural constituents. Physical properties such as thermal conductivity and damping capacity are also strongly influenced by microstructure.

The four basic types of cast iron are white iron, gray iron, ductile iron and malleable iron. White iron and gray iron derive their names from the appearances of their respective fracture surfaces: white iron exhibits a white, crystalline fracture surface, and gray iron exhibits a gray fracture surface with exceedingly tiny facets. Ductile iron derives its name from the fact that, in the as-cast form, it exhibits measurable ductility. By contrast, neither white nor gray iron exhibits significant ductility in a standard tensile test. Malleable iron is cast as white iron, then “malleablized” - that is, heat treated to impart ductility to an otherwise exceedingly brittle material.

Besides the four basic types, there are other specific forms of cast iron to which special names have been applied. Chilled iron is white iron that has been produced by cooling very rapidly through the solidification temperature range. An area of the casting that solidifies at a rate intermediate between those of chilled iron and gray iron, and which exhibits microstructural and fracture-surface features of both types, is known as mottled iron. Compacted graphite cast iron (also known as vermicular iron) has a structure intermediate between those of gray iron and ductile iron.

4. Who manages secondary and high schools in the US?

5. What is a community college?

6. How long does it take to obtain a bachelor’s degree?

7. Is education free in the US?

8. What do American institutions of higher education include?



Over 57 million students are enrolled in American schools, which range from kindergartens to high schools, small colleges, large universities, as well as a variety of institutions for adult education and vocational training. Americans place a high value on education for themselves and their children, and universal access to quality education has been one of the nation’s historic goals.

More than 100 years before the signing of the Declaration of Independence, European settlers in Massachusetts passed laws requiring all communities to hire schoolmasters; larger towns had to establish grammar schools to train children for the university. America’s first college, Harvard, was founded in Massachusetts in 1636, and the second, William and Mary, was established in Virginia in 1693.

Higher education was revolutionized in 1862 by the Morrill Act, which granted federal lands to each state for the creation of agricultural and mechanical colleges. These “land-grant” institutions legitimized vocational and technical education.

By the end of the Civil War in 1865, education was becoming available to all, and educational institutions began to shape a distinctive American culture. In the late 19th and early 20th century, the schools were instrumental in “Americanizing” the massive numbers of immigrants who arrived in the United States. Indeed, the 20th century America is the product of a nationalism defined in large part by its schools.

Perhaps the most noteworthy feature about American education is the absence of a national administration or structure. Each of the 50 states controls and directs its own schools. Most states require that children attend school from the time they reach six or seven years old until they are 16 or 17. Educational requirements are set by the state legislatures, and public schools are managed by local communities, divided into about 15, 500 state school districts.

About 85 percent of American students attend public schools which are supported by state and local taxes. The other 15 percent attend private schools, for which their families choose to pay special attendance fees. Four out of five American private schools are run by churches, synagogues or other religious groups.

In addition, schools have for many years received federal aid for special purposes, such as vocational training and school lunches. In 1965 Congress approved a major program of federal support for public schools, and federal aid was extended to private schools for the first time.

After graduating from secondary school, a growing number of Americans go on to higher education. The percentage of high school graduates enrolling in public colleges, for instance, has increased from 40.4 percent in 1960 to 54.3 percent in 1984. American institutions of higher education include technical training schools, which offer programs in fields ranging from hairstyling to computer programming; community colleges, which provide two years of semiprofessional training for some students and the first two years of college for others; colleges, offering four-year bachelor degree programs; and universities, which contain one or more colleges and graduate schools offering master’s or doctoral degree programs. The factors determining an institution’s prestige are the quality of the teaching faculty; quality of research facilities; amount of funding available; and the competence and number of applicants for admission.

Business Correspondence: a Letter of Application

A Job Interview


The letter of application is also called the covering letter and it is as important as CV. They both provide the first direct contact between a candidate and an employer. If it is not written properly, it can produce a bad impression. Usually it contains 3 or more paragraphs in which you should:


- confirm that you wish to apply and say where you learned about the job;

- say why you are interested in the position and relate your interests to those

of the company;

- show that you can contribute to the job by highlighting your most relevant

skills and experience;

- indicate your willingness to attend an interview (and possibly state when

you would be free to attend).


The opening line will be:

“Dear Sir” (addressed to a man); “Dear Madam” (addressed to a woman);

“Dear Sir or Madam” (if you don’t know who you are addressing to)

or just “Dear Mr Brown”/ “Dear Ms Smith”

Here is a sample of such a letter:

Alloy Steels

Alloy steels play an important role in all fields of industry. They are produced by the introduction of certain non-ferrous metals into low-carbon steels, notably tungsten, manganese, nickel and chromium.

One of the earliest alloy steels was introduced by R.F.Mushet who by adding tungsten to steel discovered self-hardening steel in 1868. Tools made by this method revolutionized machining processes, and it was also upon Mushet’s self-hardening steel that the experiments were based, which led to the production of the high-speed steels developed later in America.

In 1893 Robert Hadfield made an important step forward in this field by incorporating manganese in steel. This alloy was found to possess remarkable tensile strength, elongation and hardness, and became invaluable for all machinery and plant subject to abrasive action such as railway crossings, dredger buckets and the like. These types of steel, however, did not provide a steel suitable for general constructional purposes, a start in this direction being made by J.Riley of Glasgow, who in 1889 by small additions of nickel to steel markedly increased the strength and toughness without decreasing the ductility. By addition of a further alloying element, chromium, H. Brearley in 1913 founded a class of constructional steels which, in addition to strength and resistance to wear, were also resistant to corrosion.

These alloy steels heralded in the Alloy Steel Age, and so great was their development that at the outbreak of the 1939 war there were no less than 2, 000 different specifications dealing solely with alloys having various proportions of nickel, chromium and small additions of other elements. With such developments as jet propulsion, nuclear fusion as a source of power and space technology, the acceleration in alloys is likely to continue.

7. at the outbreak of 7. дальнейшая разработка сплавов

8. dealing solely with 8. быстрорежущая сталь

9. the acceleration in alloys 9. дисперсно-твердеющая сталь

Exercise 3. Answer the following questions.


1. What is the way of producing alloy steels?

2. Why was incorporating manganese in steel an important step forward?

3. Which alloy steels are good for constructional purposes?

4. Why is the acceleration in alloys likely to continue?


Exercise 4. Look through the text and find the words which mean

the same as:


a branch of industry to change completely to unite closely

appropriate to concern with exclusively

to go on


Exercise 5. More about word-building: Prefixes.

e-, ex- = out, from, away

emigrate = move out of the country = эмигрировать

eminent = standing out, distinguished = выдающийся

expel = drive out = исключить


ante- = before; post- = after; semi- = half

anteroom = a room forming an entrance to another = прихожая, приемная

postgraduate = a person who continues studying after graduation from a university = аспирант

semicircle = half of a circle = полукруг


Translate at sight:

1. Workers were paid on a semimonthly basis. 2. He has missed so many lectures, I am afraid he will be expelled from the university. 3. Workers who enter a semiskilled occupation do not have to undergo a long period of training. 4. My antecedents settled in London about a century ago. 5. After college Peter hopes to do postgraduate research in Department of Materials Science. 6. Iron is extracted from a rocky material called iron ore. 7. At the end of the lesson a group gathered around the teacher in a semicircle to ask additional questions. 8. You will not have to add a postscript if you plan your letter carefully.


Exercise 5. Give a written Russian translation of the following passages


1.There are carbon steels and alloy steels. Low-carbon steels are tough, yet easy to shape. High-carbon steels are hard and brittle, but can be given sharp cutting edges. Alloy steels contain a range of metals, each giving the steel a special property. Chromium, nickel, and steel make stainless steel, which is hard-wearing and does not rust.


2. Steel can be shaped in a variety of ways. Rolling stretches and squeezes ingots of steel into sheets, tubes, or strips. In drawing, rolled steel is pulled through a hole to make a wire. In casting, it is left to cool in a mould. Forged steel is made by squeezing hot steel.


3. Most iron is converted into steel in a basic oxygen furnace. A mixture of iron and steel scrap is poured into the furnace, and a jet of oxygen is blown over it. Oxygen combines with the carbon in the iron, carrying it away as carbon monoxide. It takes a basic oxygen furnace just 40 minutes to produce 350 tonnes of steel.

4. The ladles of molten steel are poured into moulds to make ingots, or a reservoir that serves a continuous casting process. Most steel is continuously cast because it is cheaper and better quality. These blocks of steel, called billets, can then be shaped by rolling, forging or casting.


Exercise 6. Listen to the short lecture and answer the following questions.


1. What is the main difference between ferrous and non-ferrous metals?

2. What are the properties of all metals.

3. Why is cast iron chiefly used in building?

4. What is a steel frame used for?



Task 3.

Focus on Grammar


The Gerund has exactly the same form as the present participle:

running; speaking; etc.

The perfect Gerund - having run; having spoken

The passive Gerund - being written; having been written

It can be used:

1) as subject of a sentence

Developing a new method has taken much time.

Разработка нового метода потребовала много времени.

2) after prepositions:

He is thinking of going abroad this year.

Он думает о том, чтобы поехать за границу в этом году.

She is fond of skating. Она любит кататься на коньках.

3) after certain verbs: admit, anticipate, appreciate, avoid, consider, delay, deny, dislike, enjoy, escape, excuse, fancy, finish, forgive, imagine, keep (continue), mind (object), miss, postpone, prevent, remember (recollect), resist, stop, suggest, understand.

Forgive my interrupting you. I can’t prevent his (him) going there.

Извините, что я прерываю вас. Я не могу помешать ему идти туда.

He disliked working late. Do you mind my (me) taking this book?

Он не любит работать допоздна. Вы не возражаете, если я возьму эту


4) The perfect gerund is used when we are referring to a past action:

He denied having been there. Он отрицал, что был там.

5) A number of verbs and prepositions can be followed by posessive adjective/pronoun / noun object + gerund

I insist on his writing a letter immediately. I heard about your brother’s going

Я настаиваю на том, чтобы он немедлен- abroad. Я слышал, что ваш брат

но написал письмо. едет за границу.

In less formal English we may not use the possessive case with the gerund:

Forgive me ringing you up so early. I don’t remember my brother waking up

Извини, что звоню тебе так рано.so early. Я не помню, чтобы мой брат

так рано вставал.
