Metallurgy of granules of high-strength titanium alloys

Abstract

Centrifugal spraying of a melt to obtain fine granules is a method of the technology of fast hardening. Each granule is a microscopic ingot having the composition of the sprayed alloy. Subsequent compaction of the granules gives performs or parts with uniform structure and chemical composition. This is especially important for producing large semifinished products from high-alloy titanium alloys with a capacity for segregation and structural inhomogeneity. The present work is devoted to optimization of the compaction regimes of granules of alloy VT22 and the choice of regimes of deformation and heat treatment of parts from granulated alloy VT22 in order to a obtain a combination of high properties.
