镍基金属间化合物基复合材料是目前被认为是潜在的高温材料。选择增强材料的关键因素之一是其在基质中的化学稳定性。在这项研究中，铁铝化物和几个潜在的增强材料，其中包括碳化物，氧化物，硼化物和氮化物之间的化学相互作用，从热力学考虑进行了分析。几种化学相容的增强材料被确定为铝浓度范围从40到50原子的铁铝化物。便士
Aluminide-base intermetallic matrix composites are currently being considered as potential high-temperature materials. One of the key factors in the selection of a reinforcement material is its chemical stability in the matrix. In this study, chemical interactions between iron alu-minides and several potential reinforcement materials, which include carbides, oxides, borides, and nitrides, are analyzed from thermodynamic considerations. Several chemically compatible reinforcement materials are identified for the iron aluminides with Al concentrations ranging from 40 to 50 at. pct.
