Abstract
HIP method was applied to sintering-duffusion bonding technique of the sintered structural parts. An appearance of the bonding surface and the difference of mechanical properties of the bonded material was studied. The compositions of the green compacts used in this work were Fe-0.8mass%C-2mass%Cu and SUS304L-0.2mass%B. Bonding was carried out in three combinations of Fe-Fe, SUS-SUS and Fe-SUS. As a result, the temperature of HIP treatment was lower 200-300K compared to ordinary sintering condition. The bonded compact was obtained approximately 100% relative density. This process has an advantage diffusion bonding of the same materials ( Fe-Fe and SUS-SUS), because these specimens were fractured in basis material area. However, the dissimilar material (Fe-SUS) was brittle.
