Influence of thermal treatment on stress corrosion of Fe–40 at.% Al alloy in water vapour environment

The paper aimed at the water vapour induced corrosion of the Fe–40 at.% Al alloy under applied constant loads using tensile apparatus. To interpret the registered experimental curves they were converted in accordance with Ternes method. Microfractographic investigations were conducted on specimens after cracking. Results reveal susceptibility of the iron aluminide to stress corrosion, and influence of heat treatment on this process.
