美国密歇根大学的研究人员发现,由3种以上金属元素按相同浓度组成的金属合金的抗辐射能力比纯金属高100倍。这一发现或将给核能、航空、航天等急需耐高温抗辐射材料的产业带来革命性变化。核反应装置的金属外壳暴露在高温辐射环境下,辐射粒子进入金属后,会快速“撞”走金属原子留下空穴,辐射粒子在晶体内快速穿梭,而空穴移动较慢,大量空穴逐渐合并后尺寸越来越大,会使金属外壳膨胀变形。密歇根大学的研究人员采用美国橡树岭国家实验室 Researchers at the University of Michigan found that metal alloys consisting of more than three metal elements at the same concentration have a radiation resistance of 100 times that of pure metals. This discovery or will give nuclear energy, aviation, aerospace and other industries in urgent need of high temperature radiation resistant materials to bring about revolutionary changes. The metal shell of the nuclear reactor is exposed to high temperature radiation. After the radiation particles enter the metal, they quickly “knock” away the metal atoms to leave holes. The radiation particles rapidly shuttle in the crystal while the holes move slowly and a large amount of empty Increasing the size of the hole gradually merged, will make the metal shell expansion deformation.
