Abstract
A precipitation-strengthened alloy has been produced through minor additions of zirconium to a base Ni-30 Cu alloy. The results of this exploratory study indicate that thermomechanical processing of a solution-treated Ni-30Cu-0.2 Zr alloy produced a dispersion of precipitates. The precipitates have been tentatively identified as a Ni5Zr compound. Comparison of the mechanical properties, as determined by testing in air, of the Zr-modified alloy to those of a Ni-30 Cu alloy reveals that the precipitation-strengthened alloy has improved tensile properties to 1200 K and improved stress-rupture properties to 1100K. The oxidation characteristics of the modified alloy appeared to be equivalent to those of the base Ni-30 Cu alloy.
