Popis: | 1. In annealing of sprayed high-speed steels the dispersion of the structural constituents, including the carbides, is maintained. 2. The carbide content in the sprayed powders increases after annealing, M23C6 carbide is formed, the content of M2C carbide decreases, and the ratio between the carbides changes in favor of M6C carbide. 3. After annealing the carbides cooled at rates of more than 3·103 K/sec had a uniform structure while those cooled at rates of less than 3·103 K/sec inherited areas of nonuniform structure formed in transformations of δ-ferrite. |
