Tensile properties and microstructure of the first loading region, last region and transition region of TA15alloy parts with different local loading were studied by experiment. The result shows that the room and high temperature tensile properties of the first loading region and the last loading region are better than those of transition region, but the high temperature stress rupture is no different when the local loading is applied. When a refined forming is added by whole loading after local loading process, the room and high temperature tensile properties of the transition region are better than
those of the first and the last loading region, but the high temperature stress rupture of the transition region is bad. When the local loading is applied only, the tensile properties and microstructure are better in comparison with those with local loading first and than with whole loading at last.
