METALLURGY OF GRANULES OF HIGH-STRENGTH TITANIUM-ALLOYS

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 preforms or parts with uniform structure and chemic al composition. This is especially important for producing large semif inished products from high-alloy titanium alloys with a capacity for s egregation and structural inhomogeneity. The present work is devoted t o 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 prop erties.
