研究了两种新型低活化高熵合金（HEAs）TiVZrTa和TiVCrTa，将其用作堆芯内的结构核材料，用于堆芯核应用。低活化是核反应堆的一个理想特性，旨在减少退役时的高放射性废物量，并考虑用于核聚变应用。合金TiVNbTa被用作起始成分来开发两种新型高熵合金：TiVZrTa和TiVCrTa。新合金在铸态下表现出与TiVNbTa合金相当的压痕硬度和模量。在重离子注入后，新合金显示出更强的抗辐照能力。（C）2019作者。由爱思唯尔出版集团出版。
Two new, low activation high entropy alloys (HEAs) TiVZrTa and TiVCrTa are studied for use as in-core, structural nuclear materials for in-core nuclear applications. Low-activation is a desirable property for nuclear reactors, in an attempt to reduce the amount of high level radioactive waste upon decommissioning, and for consideration in fusion applications. The alloy TiVNbTa is used as a starting composition to develop two new HEAs; TiVZrTa and TiVCrTa. The new alloys exhibit comparable indentation hardness and modulus, to the TiVNbTa alloy in the as-cast state. After heavy ion implantation the new alloys show an increased irradiation resistance.
