Abstract: An article is disclosed which is formed out of an alloy consisting essentially of 0.5-3%Ta, 1-4%Al, 1.7-5%Ti, 15-25%Co, 0-3%Cb, at least 12%Cr, at least 0.05%C, with the balance being essential nickel. The article is in the form of an aggregation of grains of said alloy, and includes discrete chromium carbide precipitates located along the outer perimeter thereof so that adjacent said grains define a substantially serrated grain boundary which offers improved mechanical properties.

Abstract: A method is described for producing metallic articles, especially turbine disks, which have a hot-worked structure in one region and a warmworked structure in another region and thereby have properties which differ in different regions. The method comprises an initial hot-working step, an intermediate heat treatment step and a final warm-working step.
