Abstract

Intermetallic alloy based on a Ti2AlNb compound are the most promising high-temperature materials for gas turbine engines operating up to a temperature of 700 degrees Celsius. In this paper, the technology of hot pressure treatment of a cast billet on a plate with a thickness of 25 mcm is studied. The technology included three comprehensive forging of the ingot billet, forging by drawing the intermediate billet and its subsequent rolling to the final size. The influence of heat treatment on the macro and microstructure of plates is studied. The chosen scheme of hot deformation and the mode of heat treatment provides an increased level of mechanical properties in the plates.
