| Popis: | We study the influence of the Q-n-P-treatment including the interrupted quenching followed by holding at 250–350°C on the microstructure, hardness, and abrasion resistance of 75KhG2C steel. It is shown that the Q-n-P-treatment leads to the formation of a structure with elevated (27.5%) content of residual austenite. The procedure treatment with quenching interrupted at 100°C followed by the holding at 250°C for 10 min increases the abrasive wear resistance of steel by 8% as compared to the fully quenched state with a much lower hardness (57 and 63 HRC, respectively). |
