In the general environment of lightweight automobiles, the integrated die-casting technology proposed by Tesla has become the general mode to better achieve weight reduction in automobiles. The die-casting mold required by integrated die-casting technology has the characteristics of large scale and complexity. Hence, higher requirements are put forward for the comprehensive performance of the die steel. Despite the stagnation in the progress of conventional strengthening methods, enhancing the performance of die steel has become increasingly challenging. Indeed, it necessitates exploring novel die steel and optimizing heat treatment and reinforcement technologies. This article summarizes and analyzes the development status of die steel and corresponding heat treatment and microstructure manipulation as well as strengthening methods and elaborates on an excellent nano-strengthening technology. Furthermore, this review will aid researchers in establishing a comprehensive understanding of the development status of die steel and the processes utilized for its strengthening. It will also assist them in developing die steel with improved comprehensive performance to meet the high demand for mold steel in the integrated die-casting technology of the new era.

Herein, nanoparticle‐reinforced carbon steels are innovatively prepared through the use of TiC‐TiB2/Al master alloys. The effects of nanoparticles on the microstructure and wear performance of carbon steels are investigated. It is found that the addition of nanoparticles inhibits the Widmanstatten structure. Also, the nanoparticles promote the formation of pearlite with finer lamellar structure and reduce the grain size. During the liquid–solid and solid–solid phase transformations, the nanoparticles act as heterogeneous cores to improve the nucleation rate. For wear tests, the presence of nanoparticles enhances the wear resistance of carbon steels. Carbon steels with 0.02 wt% nanoparticles show the lowest wear volume loss rate under each test condition. The excellent wear performance is related to the high hardness of substrates, inhibiting dislocation movement due to the refined microstructure and nanoparticles, and withstanding the external loads by nanoparticles. The findings obtained in this work can provide a new approach to fabricate high‐wear‐resistant carbon steels.

Excellent wear properties can improve the service performance and service life of high‐Cr hot work die steels. Herein, an innovative method is proposed to introduce TiC nanoparticles into the matrix of high‐Cr hot work die steels, and the effects of TiC nanoparticles on the microstructure and wear resistance of high‐Cr hot work die steels are investigated. In isothermal spheroidizing and quenching and tempering heat treatments, the TiC nanoparticles refine the granular pearlite, tempered martensite, and precipitates, which are attributed to the improved nucleation rates by increasing the number of heterogeneous cores. In sliding wear tests, the nanoparticle‐reinforced high‐Cr hot work die steels show higher wear resistance under the temperatures of 20 and 400 °C. The better wear properties of high‐Cr hot work die steels are because the substrates are strengthened and toughened, the dislocations are hindered, the mating areas are partially separated, and external loads are withstood by nanoparticles. This work shows new prospects for the development of high‐Cr hot work die steels with excellent wear performance.
