Abstract: A tungsten heavy alloy composition comprising tungsten, iron and elements selected from the groups X, Y and Z and having the formula W.sub.100-p Fe.sub.i X.sub.j Y.sub.k Z.sub.l. Such that "X" is one or more elements selected from the group consisting of Ni, Mn and Co; "Y" is one or more elements selected from the group consisting of Cr, Mo and V; "Z" is one or more elements selected from the group consisting of C, Si, Ti and Al; "i" ranges from 5 to 19.5 weight percent; "j" ranges from 0.05 to 6 weight percent; "k" ranges from 0.15 to 5 weight percent; "l" ranges from 0.05 to 4 weight percent; and "p" is the mathematical sum of i, j, k and l, and ranges from 7 to 20 such that "100-p" ranges from 93 to 80 weight percent. The blended powder mixture thus formed is hot consolidated to full density. The hot consolidated blended powder mixture is subjected to a hardening heat treatment.
