摘　　要：汽车采用超高强钢是实现轻量化兼顾安全性的必由之路,热冲压成形是高强汽车零件成形的关键工艺。近10年来,热成形钢及其零件制造技术迅速发展。本文从以下几方面对热成形钢/零件制造与使用现状进行了综述:(1)热成形钢材料(从传统MnB钢到最近新发布的一些热成形新钢种);(2)工艺(热成形传统工艺到工业4.0智能化生产);(3)热成形淬火配分(Q&P)创新工艺研究现状及形变热处理基本原理;(4)热成形过程的仿真模拟(热/力场、组织场、工艺等的模拟);(5)热成形零件的使用服役评价。并对今后热成形汽车钢制造与使用前景作出展望。Ultrahigh strength steels are highly competitive materials for vehicles to concurrently meet the increasing demand of the weight reduction and passenger safety. Hot stamping is the key forming technology to manufacture automobile components with high strength. Hot stamping steel and its manufacturing technology experienced a fast development in the past decade. This paper reviewed the state of the art of the manufacturing and applications of hot stamping steels/components in the following aspects:(1) hot stamping steels(from traditional MnB steels to recently newly developed hot stamping steels);(2) forming technologies(from traditional hot stamping process to industry 4.0 intelligent production);(3) novel hot stamping + quenching & partitioning(Q&P) process and fundamentals of deformation assisted heat treatments;(4) simulation techniques for hot stamping process(modeling of the temperature-stress field, microstructure field and simulation of the manufacturing process);(5) the assessments of in-service performance of hot stamped components. Finally, the trends of the development of hot stamping steels and related forming technologies in the future will be discussed.
