Abstract: A new process of joining semisolid AISI D2 tool steel and 304 stainless steel using partial remelting method is proposed. The results obtained from investigating the basic geometries proved a good joining quality differs from the conventional process of welding or mechanical joining with screws or nails. Metallographic analyses along joint interface between semi-solid AISI D2 and stainless steel showed that a smooth transition from one to the other and neither oxides nor microcracking are observed. The current work successfully confirmed that, avoidance of dendritic microstructure of the semi-solid joined zone and high bonding quality components can be achieved. Based on this, a new type of non-equilibrium diffusion interfacial structure was constructed at the joint interface.
