Abstract

The quenching heating temperature effect on the amount of retained austenite, the austenite stability from the strain martensitic transformation, as well as the hardening ability and abrasion resistance of high-carbon chromium ledeburite alloys (95Kh18 and 260Kh16M2 cast iron) have been investigated. The γ → α transformation and micro-TRIP-effect on the working surface of the alloys, a dissipative structure with a high degree of friction hardening and good abrasive wear resistance have been formed in this alloys.
