Abstract:The recent progresses in researches on Fe-Al intermetallic matrix composites and related research fields were reviewed. The review mainly includes the studies on the reinforcement/matrix interfacial stabilities, the fabricating processes of continuous fibers and particles reinforced Fe-Al intermetallic matrix composites, the synthesizing by mechanical alloying and sintering of particles dispersed Fe-Al intermetallic matrix nanocomposites, and the mechanical properties of Fe-Al intermetallic matrix composites. Finally, the shortcomings in these researches and the future research fields were pointed out.
