Optimizing austempering for lower bainite formation in DC53 steel: mechanisms for enhanced strength and toughness

This study aims to enhance the strength-toughness properties of DC53 cold work die steel by optimizing the austempering process. Compared to high-temperature tempering, the optimal austempering process increases unnotched impact toughness from 32.8 J/cm2 to 41.3 J/cm2 while maintaining a hardness of...
