ABSTRACT:
A powder metallurgy article formed from a Co--Cr--Mo alloy powder and a method for making the article are disclosed. The Co--Cr--Mo alloy powder contains, in weight percent, about 0.35% max. C, about 1.00% max. Mn, about 1.00% max. Si, about 26.0-30.0% Cr, about 5.0-7.0% Mo, about 3% max. Ni, about 0.25% max. N, about 1.00% max. Fe, about 0.01% max. of oxide forming metals, and the balance is essentially Co. Within their respective weight percent limits C and N are controlled such that they satisfy the relationship:
