The Ni_3Al(0.6 B)is a single phase alloy whereas the Ni_3Al(1.0 B) consists of few boride eutectic at the grain boundaries. Tensile tests and high cycle fatigue tests at room temperature are carried out in air.The results indicate that the fatigue resistance of the Ni_3Al(0.6B) alloy is higher than that of the Ni_3Al(1.0B) alloy. although, the latter is much higher than the former in tensile strength. The characteristics of fatigue crack initiation and propagation in the two Ni_3Al(B) alloys are different.Correspondent:LI Gang,Institute of Metal Research,Chinese Academy of Sciences,Shenyang 110015 Key words:  Ni_3Al      mechanical properties      microstructures      Received:  18 February 1995      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/Y1995/V31/I2/64 1青木清,和泉修．日本金属学会志,1979;43:11902MasahashiN,TakasugiT,IzumiO．ActaMetall,1988;39:18233LiuCT．WhiteCL．Horton A．ActaMetall,1985:33:2134GuoJianting,LiHui．SunChao,WangShuhe．RenDagang,XiongLiangyu,JiangJian．MaterSciEng,1992;A152:1205HerediaFE,PopeDP．ActaMetall,1991;39:20176StoloffNS,FuchsGE,KuruvillaA,ChoeSJ．In:StoloffNSetaled．,MaterResSocSympProc,1987:81:2477SureshS．FatigueofMaterials．CambridgeUniversityPress,1991 [1] Guanglu MA, Xinyu CUI, Yanfang SHEN, CINCA Nuria, M.
