摘要
概述了常见非金属元素对高熵合金的组织和力学性能影响的研究进展,分析了合金中的组织变化、强化机制对合金力学性能的影响,论述了非金属元素原子半径影响产生晶格畸变和高熵合金中的化合物沉淀,达到细化晶粒的效果,从而影响高熵合金的微观组织,最终通过细晶强化和第二相强化提高合金的力学性能.
Abstract
The research progress in effects of common non-metallic elements on microstructure and mechanical proper-ties of HEAs were summarized,and influence of microstructure evolution and strengthening mechanism on mechanical properties was analyzed.The effect of atomic radius of nonmetallic elements on lattice distortion and compound precipi-tation in the high-entropy alloy was discussed to achieve effect of fine grain refinement,thus affecting microstructure and mechanical properties of HEAs through grain strengthening and the second phase strengthening.
