摘要：
The equimolar composition AlCrCoFeNiTix (x=0, 0.5 and 1 in molar ratio) were designed with vacuum arc melting. The microstructure, phase evolution and mechanical properties were studied by SEM, XRD and the Hopkinson bar. There are two kinds of BCC phases and FCC phase simple solid solutions with x=0. With the addition of Ti, some intermetallic compounds appear. A number of criteria are considered to explain phase composition of the studied alloys. The dynamic compressive property has a different tendency. With x=0.5, the dynamic compressive strength is highest to 2.4GPa, but the best strain is 16% with x=0.
