  • Wire ARC additive manufacturing of 15-5 PH precipitation hardening martensitic stainless steel [Elektronski vir]
    Ščetinec, Aljaž ...
    The research presents Wire Arc Additive Manufacturing (WAAM) of precipitation hardening martensitic stainless steel 15-5 PH, which has a wide range of applications. The deposited material was ... precipitation hardened by solution annealing and aging heat treatments. Parametric analysis of both heat treatments was done at different temperatures and times. Material characterization was done in as deposited, solution annealed, and precipitation hardened conditions. Studies included optical microscopy and scanning electron microscopy (SEM/EDS) microstructure analysis, hardness measurement, tensile and instrumented impact toughness testing. As deposited 15-5 PH steel microstructure was composed of martensite laths along with delta ferrite. With optimisation of solution annealing homogeneous austenite and dissolve delta ferrite was achieved in WAAM microstructure. Precipitation hardening of WAAM 15-5 PH resulted in similar hardness, tensile and impact properties compared to conventionally produced 15-5 PH steel.
