STRUCTURAL MATERIALS, METAL SCIENCE

Kondratyev S. Yu., Khaydorov A. D. — Thermocyclic treatment of the cast high-speed steel R6M5 (P6M5)

Research results of the thermocyclic treatment effect on the structure of the cast high-speed steel Р6М5Ш are given. The treatment is conducted between preliminary isothermal annealing and final triple-temper hardening. It is shown that thermocyclic treatment is an effective production step, positively influencing on the microstructure of the cast high-speed steel due to amount reduction of the ledeburitic eutectic, crushing and downsizing of the carbide lattice, diminishing of the carbide inhomogeneity, carbide size and composition changes.
