| Abstract Scope |
In this study, martensitic stainless steel (MSS) and nickel-based alloy were deposited on the H13 tool steel using wire-arc additive manufacturing (WAAM). Microstructural and mechanical properties of the MSS/H13 interface have been probed using a scanning electron microscope, energy dispersive X-ray spectroscopy, Vickers indentation, uniaxial tensile testing, and impact testing. The grain size and martensitic lath size of the H13 sample gradually decreased when moving from the interface toward H13. This is attributed to the grain coarsening and dispersion of martensitic laths owing to the effect of thermal flux from initially deposited layers. The microhardness of the MSS and H13 samples following deposition was 400 HV and 420 HV, respectively. The ultimate tensile strength of the bulk MSS and MSS/H13 interface samples was ~1280 MPa and ~1000 MPa, respectively. The occurrence of hard and brittle heat-affected zones near the interface is likely responsible for the reduced strength of the interface samples. |
