| Abstract Scope |
High-strength stainless steel alloy PH13-8Mo was additively manufactured (AM) on Fe-Co-2V soft magnetic alloy substrates using laser powder bed fusion (LPBF). Hybrid AM processing and dissimilar alloy joining enabled optimization of both mechanical and soft magnetic properties, desired for small components. The PH13-8 AM build material was tensile tested in H950, H1025, and H1100 heat-treat conditions and resulted in comparable strength levels to wrought and cast PH stainless steels. The ductility of the AM 13-8PH builds is negatively affected by porosity and other AM defects. Composite specimens of PH13-8/Fe-Co-2V were also tested. As expected, failure occurred in the weaker Fe-Co-2V substrate, away from the interface, indicating strong metallurgical bonding between the dissimilar alloys. Two-step heat treatments were selected for simultaneous optimization of mechanical properties in the PH13-8Mo material and soft magnetic performance in the Fe-Co-2V substrate alloy.
