ABSTRACT:
The process relates to the improvement of the static and dynamic mechanical roperties of (.alpha.+.beta.) titanium alloys by thermomechanical treatment, wherein the alloys produced by melting and forging and/or hot isostatic pressing of powders are deformed by more than 60% with simultaneous strain-hardening at a temperature just above the recrystallization temperature of the relevant alloys in one or more steps, with structure stress-relief heatings being performed without complete recrystallization between these individual steps, the shaped part is then tempered for 2 to 4 min near the transus of the alloy, quenched and then aged at temperatures in the range of from 400.degree. to 600.degree. C.
