采用等原子比和高熵混合策略设计了AlCoCrFeNiTix(x：摩尔比；x=0，0.5，1，1.5)合金。该合金体系主要由体心立方固溶体组成，具有优良的室温压缩力学性能。特别是AlCoCrFeNiTi0.5合金，其屈服应力、断裂强度和塑性应变分别高达2.26 GPA、3.14 GPA和23.3%，优于大块金属玻璃等大多数高强度合金。(C)2007年美国物理研究所。
Alloys with composition of AlCoCrFeNiTix (x: molar ratio; x=0,0.5,1,1.5) were designed by using the strategy of equiatomic ratio and high entropy of mixing. The alloy system is composed mainly of body centered cubic solid solution and possesses excellent room-temperature compressive mechanical properties. Particularly for AlCoCrFeNiTi0.5 alloy, the yield stress, fracture strength, and plastic strain are as high as 2.26 GPa, 3.14 GPa, and 23.3%, respectively, which are superior to most of the high-strength alloys such as bulk metallic glasses.
