摘要：
In this paper, the microstructure, phase structure, hardness and micro-hardness of Co37+xNi34-xAl29(x=0,1,2,3) alloys studied by optical micrograph, X-ray diffraction, hardness test and compressive test. The results show that the beta phase and gamma phase coexist within Co37+xNi34-xAl29(x=0,1,2,3) alloys. The gamma phase at the grain boundary became coarse with Co content increasing. Meanwhile, the grain size of alloy decreases with Co content increasing. The hardness of Co-Ni-Al alloy decrease first and then increase with Co content rising. The micro-hardness of gamma and beta phase in Co38Ni33Al29 alloy is 454 HV and 713 HV, respectively.
