研究了Al含量为12 - 18 at.%的Fe-Al合金的显微组织、硬度、屈服应力、断裂应变和脆韧转变温度。研究了在所谓的K态范围内可能发生短程有序反应的Al以及碳和硅的三元添加物对Fe-Al合金硬化的影响。研究发现，即使在低C和Si含量的合金中，钙钛矿型Fe 3AlC碳化物颗粒也会沉淀;它们受预先热处理的控制，并强烈影响变形行为。
The microstructure, hardness, yield stress, fracture strain, and brittle‐to‐ductile transition temperature of Fe‐Al alloys with Al contents of 12‐18 at.% Al, which are in the range of the so‐called K‐state with possible short‐range ordering reactions, and with ternary additions of carbon and silicon were studied with respect to the effects of possible impurities on the hardening of Fe‐Al alloys. It was found that perovskite‐type Fe3AlC carbide particles precipitate even in alloys with low C and Si contents; they are controlled by prior heat treatments and strongly affect the deformation behaviour.
