FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, in particular, to production of parts from TA6Zr4DE alloy, and can be used for production of rotating parts of a turbine machine. Method of making a part of a turbine machine, made from titanium alloy TA6Zr4DE, forging a blank in an alpha/beta domain to form a preform, hot die-stamping preform to form a rough part in beta domain of titanium alloy and heat treatment. During hot die-stamping, rough part is subjected throughout to equivalent generalized deformation greater than or equal to 1.2, hot die-stamping terminating with hardening at cooling rate faster than 85 °C/min. Minimum equivalent generalized deformation is implemented and high strength is achieved.
EFFECT: longer service life of parts.
