Abstract

The data presented here are related to the research article entitled "Strengthening and deformation behavior of as-cast CoCrCuMnNi high-entropy alloy (HEA) with micro-/nanoscale precipitation [1]". Non-equimolar CoCrCuMnNi was cast by the conventional induction melting under a high-purity Ar atmosphere. Scanning electron microscopy equipped with energy dispersive spectroscopy (EDS), and transmission electron microscopy (TEM) were used for micro- and nanostructure characterization. Subsize tensile specimens with two different gage length to width ratio were tested at room and cryogenic temperatures to assess the accuracy of strength and ductility data in the as-cast CoCrCuMnNi HEAs. The mixing enthalpy (ΔH) versus lattice elastic energy (ΔH) criterion was used to predict the stable phases. The data on the effects of microstructural and nanostructural distribution of various phases on mechani-cal properties in the as-cast HEA could be used in designing high entropy alloys with excellent as-cast mechanical performance.

摘要

此处呈现的数据与题为《具有微/纳米级析出相的铸态CoCrCuMnNi高熵合金（HEA）的强化与变形行为》的研究文章相关[1]。非等摩尔CoCrCuMnNi在高纯氩气气氛下通过传统感应熔炼铸造而成。配备能量色散光谱仪（EDS）的扫描电子显微镜和透射电子显微镜（TEM）用于微观和纳米结构表征。对具有两种不同标距长度与宽度比的小尺寸拉伸试样在室温和低温下进行测试，以评估铸态CoCrCuMnNi高熵合金中强度和延展性数据的准确性。混合焓（ΔH）与晶格弹性能（ΔH）准则用于预测稳定相。铸态高熵合金中各相的微观结构和纳米结构分布对力学性能影响的数据可用于设计具有优异铸态力学性能的高熵合金。
