AbstractHelium effect on loss of uniform elongation after low-temperature neutron irradiation of the V-Ti-Cr-Si-Al-Y alloy was studied. Helium implantation to about 30 atomic ppm was carried out before neutron irradiation to 50 dpa at 406°C. The yield stress of the irradiated specimen with helium pre-implantation was slightly smaller than that of irradiated specimens without helium. The uniform elongation and the increase in yield stress of the irradiated specimens were not affected by helium pre-implantation at ambient temperature. It might be possible that the helium effect appears after lower temperature irradiation such as 300°C or lower, which corresponds to the temperature range where the loss of uniform elongation of the alloy is particularly pronounced.

Effects of different Sr additions (0.1%-1%Sr, mass fraction) on as-cast microstructure and tensile properties both at ambient temperature and elevated temperature of AS31 magnesium alloy were studied. The experimental results show that the addition of Sr could refine the grain size obviously and modify the eutectic Mg2Si from Chinese script shape to polyhedral shape or fine fibers shape. The addition of Sr to AS31 alloy improved the tensile strength at ambient temperature, and the ultimate strength at 150°C first decrease and then increase with the Sr addition increase from 0.1% to 1%Sr.
