Process optimization and microstructure study of laser powder bed fusion processed Custom 465 steel

Process optimization and microstructure study of laser powder bed fusion processed Custom 465 steel

Custom 465 (C465) stainless steel is extensively used in various industries such as aerospace, oil and gas drilling, medical and firearms industry to name a few. However, 3D printing this steel from the Laser Powder Bed Fusion (LPBF) process causes cracks to form on the finished sample. In this pape...
