论文摘要
为了寻求可以承受高级应用（例如裂变反应堆，融合设备，空间应用等）的新材料，以及对当前材料设计以外的高级材料的设计，预测和控制成为最重要目标。在这里，虽然是一种结合的实验和模拟方法，但建立了新的纳米晶体晶型高熵合金（RHEA）系统的设计。这种合金的组成在极端环境和原位电子显微镜下进行了评估，揭示了高机械强度和热稳定性，在重离子辐照下进行的晶粒细化以及对双束照射和氦植入的杰出辐射耐药性，标志着对产生异化，生长和生长，生长和结合的明显耐药性。实验和建模结果证明了明显的一致性，可以应用于设计并迅速评估受到极端环境条件的其他合金。
In the quest of new materials that can withstand severe irradiation and mechanical extremes for advanced applications (e.g. fission reactors, fusion devices, space applications, etc), design, prediction and control of advanced materials beyond current material designs become a paramount goal. Here, though a combined experimental and simulation methodology, the design of a new nanocrystalline refractory high entropy alloy (RHEA) system is established. Compositions of this alloy, assessed under extreme environments and in situ electron-microscopy, revealed both high mechanical strength and thermal stability, grain refinement under heavy ion irradiation and outstanding irradiation resistance to dual-beam irradiation and helium implantation, marked by remarkable resistance to defect generation, growth and coalescence. The experimental and modeling results, which demonstrated notable agreement, can be applied to design and rapidly assess other alloys subjected to extreme environmental conditions.
