Effect of heat treatment on non-stationary modes on structure of pseudo-α-titanium alloys used for steam turbine blades

Abstract

The effect of thermocyclic treatment of pseudo-α-titanium alloys OT4 and VT20 on their structural and substructural characteristics is considered. Signifi cant change in structural characteristics is established, this contribu tes to increase in the strength properties of alloys with satisfactory ductility and heat resistance.
