摘要	Pre-alloyed powder of Ti-22Al-24Nb-0.5Mo (atomic fraction, %) was prepared by gas atomization. Powder metallurgy (PM) Ti2AlNb alloys were prepared by a hot isostatic pressing (HIPing) route. The influence of experimental variables including HIPing temperatures, solution and aging temperatures on microstructure and properties of PM Ti2AlNb alloys was studied. The results showed that HIPing temperature affected the porosity distribution and mechanical properties of PM Ti2AlNb alloys. The microstructure and mechanical properties of the PM Ti2AlNb alloys changed obviously after various post heat treatments, and a good combination of tensile strength, ductility and rupture lifetime was obtained through an optimized heat treatment in the present work.
