Abstract

Abstract

The couple of Al-Si eutectic alloy and 1Cr18Ni9Ti stainless steel canister used in reactor was prepared by powder-metallurgy method. The compatibility and diffusion mechanics between them at 560℃ and 650℃ were investigated. The compatibility is greatly determined by diffusion temperature. At 650℃,SEM, EDS and XRD showed that the dramatic diffusion layer formed due to the infiltration and diffusion reaction. The Fe2Al5 has been found in the diffusion layer. At 560℃, there is a solid state reaction only between the Al-Si eutectic alloy and 1Cr18Ni9Ti.The diffusion layer is very thin, which has showed a very good compatibleness between them.
