STRENGTH AND TOUGHNESS IMPROVEMENT OF HIGH CARBON STEELS BY ISOTHERMAL TRANSFORMATION TREATMENT BELOW MS TEMPERATURE

Changes in some high-carbon steels were studied while being held isothermally at below their Ms point, about 200 C, following quenching from the austenitizing temperature. It was ascertained that isothermal transformation from austenite to bainite occurs and is completed in these ranges. Effects of the treatment on strength and toughness were found to be that high-hardness steels are markedly improved by this process, but strength and toughness vary considerably, not only with treatment but also with treatment time.
