难熔高熵合金高通量激光金属沉积合成及其结构性能表征

  • 摘要: 材料的研发进程通常与生产和评价大量含有不同化学成分合金的时间需求密切相关,尤其是对于难以用常规方法合成和加工的难熔高熵合金(RHEAs)更是如此。为了评估可能加速合金开发过程的途径,本工作采用高通量激光金属沉积技术,通过元素粉末的原位合金化制备五元TiZrNbHfTa难熔高熵合金及其四元和三元子系统,并分析了五元合金的成分分级变体。结果表明可以对粉末的形状和纯度、合金成分,特别是固化范围等参数对合金的成型性能、微观结构、孔隙率和力学性能的影响进行快速分析。这些合金的强度主要受原料粉末中氧和氮含量的影响,相比之下,置换固溶强化对合金强度的作用则较小。
