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.
