Abstract

A sintered alloy is formed by compacting and sintering a powdered mixture of Zr and/or B and a Ni-Cr base prealloy having the following composition: .C.up to 0.35% .Cr.8-25% .Co.0-30% .Mo and/or W.0-10% .Ti.0-7% .Al.0-8% .B.0-0.02% .Zr.0-0.04% .Nb.0-3% .Fe.0-10% Ni and impurities Balance The Zr which is added as the powdered metal, or compound such as a carbide or boride, or alloy forms 0.01-0.4% by weight of the sintered alloy and is preferably added as the boride. The boron which forms 0.01-0.15% by weight of the alloy is added as the boride of Zr, Cr, Co, Ni, Nb, Ta, Fe or Mn. The Specification includes many examples of different percentage additions of Zr and B to the Ni-Cr base prealloys.
