PREFACE

The present study quide is intended for students of a specialty 7.030507 “Translation”, and also for students of other specialties studying technical disciplines in English. The laboratory works, submitted in the textbook, cover the basic sections of the discipline “Material Science and Technology of Structural Materials”: material science of steels and cast irons, ferrous and nonferrous metallurgy, foundry practice, metal forming, welding, machining of workpieces. The English – Russian – Ukrainian Dictionary is presented in the study quide.

The description of laboratory works can be divided into two parts. In the first part the brief theoretical data necessary for preparation for independent performance of a laboratory work are given; in the second one methodical instructions on performance of works and drawing up of written reports are presented.

With the purpose of more complete mastering of the discipline and acquisition of practical skills, elements of primitive research are incorporated in the majority of laboratory works. Thus an academic group is divided into 5…6 subgroups, and each of them receives an individual task. Results of calculations and the tests, obtained by each subgroup, are generalized as a graph or a table being analyzed by the whole group and recorder down in wriiten reports.

Students have to be instructed on the safety precautions at the beginning of each laboratory work. With the aim of time savings the monitoring of students’ knowledge is carried out by means of tickets with special tests or by automated facilities.
