... are at the expense of a 73% decrease in elongation compared with the EBM material. In general, both EBM and LPBF Co-Cr alloys possess improved yield and tensile strength values as compared with both as-cast ( Ref 32 ) and wrought ( Ref 33 ) Co-Cr alloys. ASTM standard F75 stipulates a yield strength of 450 MPa...
