Abstract: Hot work die steels are extensively applied in hot forming, where dies are subjected to high temperature and mechanical stresses and are prone to fatigue failure. A novel approach was proposed to synergistically manipulate hot work die steels by increasing Cr content and introducing TiC nanoparticles, showing far superior oxidation resistance and hot-cold alternating fatigue resistance compared to the international high-end DIEVAR die steels. On the one hand, the introduction of ceramic nanoparticles contributed to the enhanced oxidation resistance of the steels by promoting the formation of a thicker and denser Cr 2 O 3 oxide film on the steels surface. On the other hand, the high-temperature microstructure stability and tempering resistance of steels were also improved through microstructure refinement and matrix strengthening. This effectively inhibited the initiation and propagation of hot-cold fatigue cracks, thereby significantly improving the resistance of steels to hot-cold alternating fatigue. This work provides a theoretical basis for understanding the modification of the high-performance hot work die steels. • Synergistically enhanced die steel surpasses international high-end DIEVAR steel. • The oxidation and hot-cold fatigue resistance are simultaneously improved. • Nanoparticles promote the formation of thick and dense Cr-rich layer. • Refined, uniform, and stable microstructure enhances hot-cold fatigue resistance.
