本文综述了镍、铁铝化物金属间化合物合金的最新研究进展。有序金属间化合物在恶劣环境中的高温结构应用中具有诱人的性能，但脆性破坏和较差的抗断裂性能限制了它们作为工程材料的应用。近年来，对这种脆性断裂行为的研究已经确定了控制脆性断裂的内在因素和外在因素。利用物理冶金原理进行合金设计的并行工作导致了结构用铝化物合金的发展，这些合金具有更好的机械和冶金性能。
This article summarizes recent progress in research and development on nickel and iron aluminide intermetallic alloys. Ordered intermetallics possess attractive properties for structural applications at elevated temperatures in hostile environments; however, brittle failure and poor fracture resistance limit their use as engineering materials. In recent years, efforts to understand this brittle fracture behavior have identified both intrinsic and extrinsic factors governing brittle fracture. Parallel work on alloy design using physical metallurgy principles has led to the development of aluminide alloys with improved mechanical and metallurgical properties for structural use.
