Abstract: Helium implantation of 50at.ppmHe by cyclotron accelerator was adopted to study helium effect on tensile properties of the V-5Ti-5Cr-1Si-Al-Y type alloy. Tensile tests were conducted at temperatures ranging from room temperature to 850℃ with strain rates from 6.7×10^ to 6.7×10^/s. Increase of yield stress was not appreciable in helium-implanted specimens except for 450℃. Intergranular fracture mode was observed specimens tested at temperatures above 450℃. Decrease of elongation was observed at all testing temperatures. Relationship between tensile strength and decrease of elongation was discussed.
