주철과 오스테나이트계 스테인리스강과의 확산접합에 관한 연구

Abstract

Effects of the diffusion bonding on the mechanical properties for the GCD45 /austenitic stainless steel(STS304) bonding specimens have been investigated. The results are obtained as follows ; 1) In the case of GCD45/STS304 specimen made on air, the bonding tensile strength increased with increasing bonding temperature. The maximun bonding tensile strength was 467.5MPa at 1373K. 2) The bonding tensile strength of GCD45/STS304 made by using insert metal MBF35 increased with increasing bonding time, and was about 470MPa at the conditions of bonding temperature 1323K, bonding time 1.8Ks and bonding pressure 9.8MPa. 3) The bonding tensile strength of GCD45/STS304 made by using the insert metal was higher than that of direct bonding specimen.
