Abstract

To manufacture tools from medium- and high-alloy steels or stellites by superplastic precision-forming, a powder-metallurgically produced starting material of equiaxial structure with more than 30 % by volume of a carbidic and/or boridic precipitation phase of a particle size of 1 to 0.2 mu m is adjusted by thermomechanical processing (hot-forming) to a matrix grain size of 1 to 3 mu m and formed in the superplastic state. <IMAGE>
