Effect of Deep Cryogenic Treatment Duration on the Microstructure and Wear Resistance of Hot‐Work Die Steel
This study investigated the effect of deep cryogenic treatment (DCT) duration on the microstructure, hardness, and wear resistance of two experimental H13 hot‐work die steels with different chemical compositions. The steels were quenched, subjected to DCT at –196 °C for 10, 20, and 30 h, and subsequently double tempere...
