对激光粉末床熔融增材制造的CoCrFeNiTiMo多元合金进行了微拉伸试验，结果表明，在屈服点处激活的滑移系为八面体滑移和立方滑移，这取决于加载方向。热处理有序析出抑制了立方滑移，提高了强度和应变硬化能力。
Micro-tensile tests on CoCrFeNiTiMo multicomponent alloys additively manufactured by laser powder bed fusion revealed that the slip system activated at the yielding point was octahedral and cubic slips depending on the loading direction. Ordered precipitation by heat treatment inhibited the cubic slip and enhanced the strength and strain hardening ability.
