Abstract
As a result of scientific and technical progress, the economy and machine-building industry are developing rapidly. The development of the economy and industry requires serious research on the search for high-strength, easy-to-use, inexpensive, thorough materials and increase the durability of the joint. The science that studies the composition, structure, and properties of alloys, as well as the relationships between the structure and properties of a bond and the methods of refining, is called material science. Metal is the most widely used material in our daily lives.
