1. Laser Based Powder Bed Fusion of Plain Carbon and Low-Alloy Steels: Microstructure and Processability
Abstract : Despite the prominence of laser based powder bed fusion (LB-PBF) as an additive manufacturing technique, the number of alloys that have been approved for the process remains limited. In traditional manufacturing, ferrous alloys are the most common alloy group, consisting primarily of plain carbon and low-alloy steels. READ MORE
