چکیده انگلیسی
α+β titanium alloys have been widely used in many industrial fields. Two novel alloys with the name of Ti-6Al-4Me(Cr, Mo) have been fabricated in laboratory scale. β phase solution heat treatment and high temperature aging were performed to study the microstructure variations. A systematic microstructural investigation has been carried out. The results show that samples soaked in β phase field, αⲠmartensite were formed during the quenching, but in Ti-6Al-4Cr alloy, the microstructure is more uniform. After aging treatment, both alloys present a typical Widmanstätten microstructure. With the increase of the aging temperature, the size of α platelet in Ti-6Al-4Cr alloy coarse more apparently as compare to the Ti-6Al-4Mo alloy. Furthermore, in Ti-6Al-4Cr alloy, samples with 600 °C aging, TiCr2 Laves phase was observed along the α/β interface, and in some part of α phase, special Cr solid solution bands were also found.
