Conclusions
-
1.
A change in the phase composition of steel Kh12F1 and an increase of the dislocation density in α and γ phases occur at a depth of as much as 300 μ and depend on the quenching temperature.
-
2.
The wear resistance is highest for blades quenched from 1050–1130°, in which the quantity of retained austenite does not exceed 40%. Quenching from 1130° is preferable. This ensures a fairly high structural strength in combination with high wear resistance due to hardening in the process of operation.
