摘要
通过试错法在AlSiTiCrMnFeNi合金体系中寻找有望成为高温结构材料的多元单相高熵合金,并通过DSC和硬度测试判断其性能.试验发现一种具有HCP结构的 6 元单相高熵合金,其成分为τ-Si19.8Ti26.4Cr10.1Mn13.3Fe18.6Ni11.8,硬度(HV)高达 963.6,在1 400℃ 以下不发生相变,相结构稳定,具有优良的硬度和热稳定性.
Abstract
The multi-component and single-phase high entropy alloy which is expected to be a high temperature struc-tural material in AlSiTiCrMnFeNi alloy system was developed by trial and error method,and properties were deter-mined by DSC and hardness test.A hexahydric single-phase high-entropy alloy with HCP structure was discovered,of which the composition is Si19.8Ti26.4Cr10.1Mn13.3Fe18.6Ni11.8,and the hardness value is as high as 963.6 HV.The alloy does not undergo phase transition at temperature below 1 400 ℃,indicating a stable phase structure,leading to excel-lent hardness and thermal stability.
