The effects of holding time and pre-alloyed powder manufacturing methods on microstructure， tensile properties and tensile fracture morphology was investigated for powder metallurgy （PM） TA15 alloys. In this work， hot isostatic pressing （HIPing） technique was used to densify the TA15 pre-alloyed powder. The results show that the microstructure of PM TA15 alloys is composed of equiaxed α grains， lamellas α grains and a little β grains. When the holding time is 20 min during HIPping， the PM TA15 alloys have gotten full densification. As the holding time extends to 2 h， the microstructure became coarser. The tensile properties of PM TA15 alloys with plasma rotating electrode process powder are better than those of PM TA15 alloys with gas atomization powder. The tensile fracture mode is ductile fracture， and fracture morphology appearance is the dimple.
