Abstract

Materials science is conditionally divided into theoretical and applied one. The former one deals with general regularities of structure of materials and processes which occur in them under external effects. It is based on integration of achievements in physics, chemistry, physical chemistry, electrochemistry, physics of metals and other natural sciences development of which affects the amount of use of materials in technology and effectiveness of methods for processing them into articles. This connection, not so evident in the past, today shows effective ways of creation of materials and development of manufacturing methods which meet the increasing engineering and economic requirements. The objective of applied materials science is to seek for optimal structure and technology for processing materials when manufacturing parts of machines and other mechanical articles.
