Abstract

In the nomenclature of structural materials for machinery construction there are a lot of nonferrous metals and alloys which possess special properties: heat resisting, antifriction materials, those for aviation and rocket engineering, etc. The necessity to develop special property alloys is conditioned by the development and improvement of technology: increase of working loads and speeds, expansion of working temperature and pressure range, the necessity to increase the specific strength of traditional engineering materials. Heat resisting materials and titanium-, tantalum-, niobium- and tungsten-based alloys are of a particular interest. The interest of industrial manufacturers to materials with high specific strength properties has traditionally been high.
