Abstract
This study investigated the tensile and fracture behaviour of additively manufactured MS1-H13 hybrid hard steel. Samples were prepared using Direct Metal Laser Sintering (DMLS) technique to additively deposit MS1 powder on as received H13 tool steel round bars. Four different heat-treatments were subsequently applied to the samples and uniaxial tensile tests to fracture were completed. Results found peak hardness/strength could be achieved with a single heat-treatment cycle and fracture in peak hardened samples occurred in MS1 adjacent to the print interface, as verified by Energy Dispersive X-ray (EDX) analysis. As-printed samples fractured in the H13 material away from the interface.
