Effect of helium implantation on tensile properties of V-Ti-Cr-Si type alloy

Description
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 850degC with strain rates from 6.7 x 10-5 to 6.7 x 10-3/s. Increase of yield stress was not appreciable in helium-implanted specimens except for 450degC. Intergranular fracture mode was observed specimens tested at temperatures above 450degC. Decrease of elongation was observed at all testing temperatures. Relationship between tensile strength and decrease of elongation was discussed. (author)
