| Abstract Scope |
PH 13-8 Mo steels are a family of martensitic precipitation hardening stainless steels (MPHSS) known for their good combination of mechanical strength and corrosion resistance. Additive manufacturing is gaining attention to produce MPHSS components in the tooling and aerospace industries. However, research on directed energy deposition using a laser beam (DED-LB) of the PH 13-8 Mo alloy family is sparse. A block (110 mm x 110 mm x 13 mm, 32 layers) was produced by DED-LB and subjected to different post-processing heat treatments. This study investigated the microstructure using electron microscopy, electron backscatter diffraction, and hardness of the as-deposited and heat-treated modified PH 13-8 Mo, as well as the anisotropy in tensile properties of the as-deposited material. |
