Abstract
In response to the unclear mechanism of mechanical property changes in high entropy alloys and the sensitivity of material property changes,a titanium containing high entropy alloy sample was studied and prepared.The effects of rolling direction,rolling temperature,and annealing temperature on the mechanical properties of titanium containing high entropy alloys were analyzed.The results show that different rolling directions can affect the grain boundary structure of the alloy,thereby altering its mechanical properties.High temperature annealing can significantly reduce the yield strength and tensile strength of alloy sheets,while the change in elongation is small,only increasing from 3.0%to 5.0%.The increase in the proportion of low angle grain boundaries can to some extent reduce the yield strength and tensile strength of alloy sheets.关键词
