This review is focused on the perspectives of the application of Advanced High Strength Steels (AHSSs) in the field of additive technologies directed at the laser powder bed fusion/selective laser melting processes. In principle, AHSSs require significant attention due to their promising mechanical properties for usage in the automotive industry towards reducing the weight of vehicles. Although additive manufacturing represents a promising perspective towards expanding the industrialization of AHSSs in a wider area of their applications, they have not been sufficiently investigated concerning their usage in LPBF/SLM processes. AM techniques enable the fabrication of complex machine parts, including those with a cellular structure, which can contribute to further reducing the weight of vehicles or structures. Maraging steels have recently attracted the attention of researchers, and today are a common grade of steel produced by LPBF techniques. The other group of AHSSs are high-Mn steels with an austenitic matrix characterized by the TRIP and TWIP effects. Less published research has been conducted on medium-Mn steels, which require additional intercritical annealing and preheating during printing. Moreover, the advanced bainitic steels and low-density, high-strength steels represent a new window for further research into the use of the LPBF processes for their fabrication.
本综述聚焦于先进高强度钢（AHSSs）在面向激光粉末床熔融/选择性激光熔化工艺的增材制造技术领域的应用前景。原则上，AHSSs因其在汽车工业中有望用于减轻车辆重量的机械性能而需要予以高度关注。尽管增材制造对于在更广泛应用领域扩大AHSSs的工业化来说是一个有前景的方向，但它们在激光粉末床熔融/选择性激光熔化工艺中的使用尚未得到充分研究。增材制造技术能够制造复杂的机械零件，包括具有蜂窝结构的零件，这有助于进一步减轻车辆或结构的重量。马氏体时效钢最近引起了研究人员的关注，如今是通过激光粉末床熔融技术生产的常见钢种。另一类AHSSs是具有奥氏体基体且表现出相变诱发塑性（TRIP）和孪晶诱发塑性（TWIP）效应的高锰钢。关于中锰钢的研究较少，中锰钢在打印过程中需要额外的临界区退火和预热。此外，先进贝氏体钢和低密度高强度钢为进一步研究使用激光粉末床熔融工艺制造它们提供了新的窗口。
