It was found that the YNi_5 phase in Ni_5Al alloy could remarkably make its grains finer and its grain boundaries more crooked other than straigh. If the Y content≤0.1 wt-％, it occurs as solid solution state and is favourable to high temperature compressive properties and oxidation resistance of the alloy. While Y≥0.3 wt-％, the formation of YNi_5 is predominant in the shape of irregular strips inside Ni_3Al grains and along their grain boundaries. This seems to be quite harmful to high temperature strength, ductility and oxidation resistance of the alloy. Key words:  Ni_3Al      YNi_5 phase      Y      compressive property      oxidation resistance      Received:  18 June 1991      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1991/V27/I6/39 1 青木清,和泉修,日本金属学会会志,1979;43:1190 2 郭建亭,李辉,孙超,朱耀霄.金属学报,1989;25:A406 3 Holt R T, Wallace W.
