ABSTRACT

Aspiration to making of effective gas-turbine engines and power installations has stipulated for a great demand in new super materials, as rise of turbine efficiency is first of all connected with increasing of its operating temperatures. Application of metallic structural alloys at high tem¬peratures accompanies by interaction with the strongly aggressive environment, abrupt lowering of their strength, unstability of structures and properties.
