Abstract:

The effect of retained austenite on the bending fatigue durability of carburized 9310 steel was investigated. It was found that nonfrozen test bars, containing 13.8 to 18.5 retained austenite had superior fatigue resistance than frozen test bars, containing 5.3-7.3 retained austenite. The mean fatigue life ratio of nonfrozen to frozen bars at 155 KSI was determined to be 3.5, with a 99 confidence. Author
