| Abstract Scope |
The field of metal additive manufacturing (MAM) is rapidly advancing; however, it faces several challenges including the production of new alloy systems and powder composite manufacturing methods. Previous studies have investigated metal matrix composites produced by selective laser melting (SLM) which resulted in finer grains, improved hardness, and tensile strength due to the homogeneous distribution of reinforcement particles. To address some of the challenges in alloy development for MAM, this work has the intent to investigate ball milling technology and its capability of producing printable powder. Additionally, in order to obtain equiaxed, fine grained microstructures and provide useful guidance to achieve better mechanical performance for Co-Cr parts, the incorporation of carbides and their precipitation at atomic scale during the laser sintering is studied using pulsed and continuous laser. The observations point to the applicability of high energy ball milling as a platform for alloy and composite design for MAM. |
