Optimization factors in hardening of AISI 5106 carbon steel. (English)

The objective of this research was to determine the optimum factor of the hardening process of carbon steel. The study factors were quenching temperatures at 750, 800 and 830 °C, with 2 and 5 min of holding times, and the quenching media were oil and water. The hardness of the specimens was measured. It was found that the optimal conditions for hardening were at a hardening temperature of 764 °C, hardening for 5 minutes holding using oil quenching. It was found that the average hardness of workpieces was 48 HRC. It was also found that the quenching temperature affected the hardness of the work-piece but the holding times and the quenching medium did not affect the workpiece hardness at 0.05 significance level.
