Abstract
In this work,WMoNbTaTix(x=1.2,1.4,1.6,1.8,2.0)high entropy alloy was prepared by non-consumable vacuum arc melting method,the alloy structure and properties were characterized to study the effect of Ti contents on the microstructure and mechanical properties of the alloy.The results indicate that WMoNbTaTix is composed of BCC single-phase structure,and the alloy microstructure is dendritic structure.There is segregation in the constituent elements.When x=1.2-1.6,the alloy grain size increases with the increase of Ti content.When x=1.8,the alloy grain size significantly decreases and then increases again.With the increase of Ti content,the plasticity of the alloy shows a trend of first increasing and then decreasing,while the strength first increases and then increases,reaching its maximum value at x=1.8,and then decreases again.关键词
