Abstract

Modern development of innovative equipment (primarily aviation and aerospace) makes demands to materials capable to work at high temperatures in which traditional nickel alloys cannot work. The problem of creating new heat resistant including refractory alloys acquires nowadays particular significance not only in the aircraft industry in connection with development of high-economic gas turbine engines of new generation, but also in other industries. One of the promising scientific and research directions in this field is the refractory metals and alloys development which keep considerable durability up to temperatures of 1300–2500°C. Among the metals of the kind the «big four» – tungsten, tantalum, molybdenum, niobium are outstanding that both in pure or as alloys widely used in various industrial fields.
