Abstract
The interaction between solid iron and liquid aluminium is studied by immersion tests. At first, the intermetallic layers formed at the soli d-liquid interface and their growth mechanisms are characterized. The Fe2Al5 and FeAl3 phases are identified in the temperature range from 7 00 to 900 degrees C, and their growth is found to be mainly controlled by a diffusion regime. Then, a theoretical approach of the phase grow th based on the solutions of the diffusion equations is presented. The ory and experiment agree rather well. (C) 1998 Elsevier Science S.A.
