| Abstract Scope |
Powders with the composition of 70(Co28Cr6Mo) - 30Cu were fabricated by induction crucible inert gas atomization from LPBF-fabricated feedstock of pre blended powders. The particles were cross sectioned and classified by size to characterize composition, spherulite size, and distribution on multiple size scales. Selected powder sizes were LPBF fabricated and pressed & sintered using solid state and liquid phase sintering. The solids were characterized to determine the effect of processing on multiscale microstructure features and spherulite distribution as compared with the powder feedstock. Vicker’s and nanoindentation measurements were taken on the solids to evaluate the effect of composition and spherulite configurations on hardness. |
