Iron alloys containing 9 to 16 wt% Al were prepared by vacuum fusion in an induction furnace. The hardness, hot hardness, linear expansion coefficient, and electrical resistance were measured as a function of the Al content. Microstructural analyses on quenched and annealed samples showed the absence of any changes due to transformations of Fe3Al. All the curves showed definite minima at 14.3 wt% Al (25.8 at.% Al) which is close to the composition of Fe/sub 3/Al. The hot hardness curves indicate the existence of a compound at 12.0 wt% Al below 600 deg C. The heat strength of the Fe--Al alloys increases with increasing aluminum content, and Fe--Al alloys containing 16 to 18 wt% Al as a solid solution in alpha iron possess the highest heat strength.
