Abstract
The paper reports results of the studies on the influence of deformati on degree and temperature in the die forging process and annealing tem perature on the fatigue strength of forgings made of two phase martens itic titanium alloys Ti-6Al-3V and Ti-6Al-2Mo-2Cr. Dilatometric and me tallographic studies have been carried out along with X-ray phase anal ysis and fatigue tests. The influence of the phase composition and mic rostructure obtained after cooling with different rates on the fatigue strength have been determined. (C) 1998 Elsevier Science S.A.
