Effect of C Content on Microstructure and Properties of (FeCoCrNi)88-xMo8WNb3CxHigh Entropy Alloys by Additive Manufacturing

  • 摘要: 采用机械合金化方法与增材制造技术制备了(FeCoCrNi)88-xMo8WNb3Cx(x=0.25、0.5、0.75、1、1.5、2、2.5)高熵合金成型件。在明确该高熵合金形成规律的基础上,进一步分析了C含量对其组织和力学性能的影响规律。结果表明:当C含量介于0.25%~2.50%(摩尔分数)之间时,(FeCoCrNi)88-xMo8WNb3Cx高熵合金均由FCC相和M6C相组成;随着C含量的增加,合金的抗压强度逐渐增加,塑性呈先增大后减小趋势;当C含量为2.00%时,合金的综合力学性能最优,其抗压强度为1 993.4 MPa,断裂应变为31.5%。
