Conclusions
-
1.
The method of planned experiments was used to obtain a mathematical model describing the effect of temperature and carburizing time and quenching temperature on the probability of fracture of samples of steel KhVG in static tests.
-
2.
The quenching temperature was the largest effect on the probability of failure of carburized samples of steel KhVG.
-
3.
The optimal quenching temperature is 780–810° after carburizing at 840–900° for 6 h.
