The physical and mechanical metallurgy of Ni3Al and its alloys was reviewed. Emphasis was placed on developments within the previous five years, a period of extremely rapid growth in research on the behaviour of the unusually interesting intermetallic compound. The review was particularly concerned with solute effects upon properties such as diffusion rates, ductility, fatigue resistance, and environmental stability, subjects that only recently have received much attention. Novel processing techniques, including rapid solidification and powder processing, were shown to have played a key role in providing Ni3Al-base alloys with improved properties. An assessment of needed areas of research to hasten commercial applications of Ni3Al alloys concludes the review.
