Abstract

The results of the work of the NRC «Kurchatov institute» – VIAM for the development of production of semi-finished products from heat-resistant titanium pseudo-α-alloy VT41. The directions of adjustment of the alloy composition, and the prospects of wider application of alloy in the manufacture of welded components of gas turbine engines are presented. Foreign experience of manufacturing of deformable semi-finished products from the analog alloy Ti-834 (IMI 834) is given. The peculiarities of microstructure and its components formed at various conditions of heat treatment are considered.
