通过混合具有有利核活化特性的元素来制造高熵合金，有可能制造出一种能够承受核聚变环境的材料，同时最大限度地减少产生的放射性废物。这种材料可用于聚变包层的极端热和辐射条件。一套以前未开发的V-Cr-Mn和V-Cr-Mn-Ti合金已被制造，然后均匀化，并表征所得的显微组织和相。结果表明，在含有低活性元素的高浓度合金中可以形成单相体心立方固溶体显微组织，这对于熔合合金的发展观点来说是有希望的。(C)2019 Acta Materialia Inc.爱思唯尔有限公司出版
By mixing elements with favourable nuclear activation properties to create high-entropy alloys, it may be possible to create a material that can withstand a nuclear fusion environment while minimising the radioactive waste produced. Such a material could be used in the extreme thermal and irradiation conditions of a fusion blanket. A suite of previously unexplored V-Cr-Mn and V-Cr-Mn-Ti alloys have been fabricated then homogenised and the resultant microstructures and phases were characterised. Results demonstrate that single-phase body centred cubic solid solution microstructures can be formed in highly-concentrated alloys incorporating low-activation elements, which is promising for a fusion alloy development standpoint.
