Effect of room temperature aging on low temperature transformation of retained austenite
- 75 Downloads
The effect of room temperature aging on the stabilization and low temperature transformation of retained austenite in a low alloy steel (SAE 52100) was studied. It was found that the amount of retained austenite which transformed on subcooling to 250 °K, 200 °K, and 150 °K decreased rather rapidly as the aging time at room temperature prior to cooling was extended up to 16 hours. Little retained austenite transformed by further extending the aging time at room temperature beyond 16 hours.
