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: 62.866 + 360.93 x (%C) + 286.633 x (%N) - 682.165 x (%C)2 - 641.702 x (%N)2 >= 120. |
