Abstract

The elevated temperature compressive tests were carried out in order to investigate the deformation behavior and microstructural characteristics of Al-8%Ti, Al-12%Ti and Al-16%Ti (wt%) alloys, which were mechanically alloyed and consolidated by vacuum hot pressing, A13Ti intermetallic phases were formed with sizes of few hundred nanometers in the mechanically alloyed Al-Ti alloys. The compressive strength of mechanically alloyed AA-Ti alloys increased with decroasing the temperature and with increasing the strain rate. The strain rate sensitivities of Al-8%Ti, Al-12%Ti and Al-16%Ti alloys were measured 0.02,0.03, and 0.14, respectively, at 35$0^{\circ}C$.
