Abstract

Abstract

The effect of tempering temperature on microstructure and impact toughness of low-carbon, high-alloy bearing steel was studied by OM, SEM, and XRD. The results show that the metallographic microstructure for the low-carbon, high-alloy bearing steel consisted of tempered martensite and retained austenite when the tempering temperature is 200, 300, 400, 500 ℃, respectively. Furthermore, martensite degradation occurs, and the microstructure consists of tempered soxbite and retained austenite when the tempering temperature increases to 600 ℃ and 700 ℃. After tempering at 200-700 ℃, the impact toughness of low-carbon, high-alloy bearing steel tempered at 300 ℃ is the highest, that tempered at 600 ℃ is the lowest, and the tempering temperature should not exceed 500 ℃. The fracture characteristics of low-carbon, high-alloy bearing steel after tempering at 200-500 ℃ are quasi-dissociative fractures, and the tempering at 600 ℃ and 700 ℃ are brittle fractures.
