摘要
热作模具钢作为制造高温金属成型模具的关键材料,其服役性能直接决定金属热加工工艺的效率与可靠性。由于热作模具钢需在高温下承受交变热应力与机械磨损,对材料热疲劳抗性和耐磨性提出了严苛的要求。因此,需要深入探究提高热作模具钢使用寿命的方法。通过文献综述的方式总结了热作模具钢的主要失效形式以及提高热作模具钢热疲劳性寿命和耐磨性的方法,如表面处理、优化合金、热处理等传统技术路线,此外,介绍了一种新的纳米颗粒强化方法,通过在钢液中加入纳米颗粒,使其均匀分散,从而细化热作模具钢的微观组织,提高其使用性能,将成为未来研究的重点方向。
As a key material for manufacturing high-temperature metal forming molds,the service performance of hot work die steel directly determines the efficiency and reliability of metal hot processing process.Since hot work die steels are subjected to alternating thermal stress and mechanical wear at high temperatures,strict requirements are placed on the thermal fatigue resistance and wear resistance of the materials.Therefore,it is necessary to explore the methods to improve the service life of hot work die steel.In addition,a new nanoparticle strengthening method is introduced,which will refine the microstructure of hot work die steel and improve its performance by adding nanoparticles to the molten steel to make it evenly dispersed,so as to refine the microstructure of hot work die steel and improve its performance,which will become the focus of future research.
