Abstract
PM23 powder steel and H13 hot working die steel and 9Cr2Mo cold working die steel bimetallic composite components were successfully prepared by hot isostatic pressing powder-solid diffusion bonding process. The interfacial behavior of H13-PM23 and 9Cr2Mo-PM23 bimetals was studied by SEM and EBSD techniques; the mechanical properties of the two bimetals were evaluated by universal testing machine. The results indicated that the element diffusion occurred in the interfacial bonding region, and an obvious decarburized layer was observed in the 9Cr2Mo-PM23 bimetals, whose surface was enriched with small rod-like and dot-like MC and MC carbides.
