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°C with strain rates from 6.7×10 -5 to 6.7×10 -3/s. Increase of yield stress was not appreciable in helium-implanted specimens except for 450°C. Intergranular fracture mode was observed specimens tested at temperatures above 450°C. Decrease of elongation was observed at all testing temperatures. Relationship between tensile strength and decrease of elongation was discussed.
