Abstract: Preparation of iron-base alloys, particularly in the form of regenerator cores and other similar matrices, by the codiffusion of aluminum and chromium, using aluminum-iron alloy powder and chromium, aluminum-iron alloy powder and chromium-iron powder or Al-Cr alloy powder as sources of the aluminum and chromium and an atmosphere of mixed H2 and HF to accomplish in situ formation of the aluminum and chromium and their diffusion, and alloying with the iron-base alloy. Assemblies may be bonded to form an integrated structure along with the heating for coduffusion of aluminum and chromium.
