The tested alloy in initial state is characterized by microstructure consisting of alpha phase with small amount of beta phase particles distributed in the network throughout the a matrix (Fig. 1).
Mechanical properties of Ti-8Al-1Mo-1V-0.2C tested in ambient temperature Alloy State UTS [MPa] YS [MPa] EL [%] RA [%] Ti-8Al-1Mo-1V-0.2C DA 1181 1141 17.6 33.9 STA 1258 1222 13.7 18.7 Ti-8Al-1Mo-1V [14÷17] DA 896÷950 827÷890 10.0 - STA 1180 1070 17.0 26.0 Short-term creep tests (Fig. 5) carried out for the tested alloy at 500ºC and 300 MPa show that its creep resistance is higher in state after duplex annealing (DA).
