AISI H13 steel samples were additively manufactured using a laser powder bed fusion (LPBF) system. The effect of annealing tem-perature, quenching & tempering, and nitriding determined. microstructure properties the investigated optical microscopy, scanning electron backscattered diffraction, probe micro-analysis, X-ray roughness measurement, hardness tester. results show that as-built samp...

In this work, AISI H13 tool steel build-ups were produced through wire arc additive manufacturing (WAAM). The cold metal transfer (CMT), low spatter control (LSC) and pulsed synergic (PS) current deposition modes compared. Similar strategy was employed in order to attempt evaluate the influence of energy input on geometrical mechanical properties deposits. To deposits, hardness tensile tests ca...
