摘　　要：提高汽车用钢的强度是实现汽车轻量化设计的有效途径。然而,随着热成型钢强度不断提高,其氢脆敏感性也相应增大,氢致开裂已成为阻碍超高强度热成型钢发展与应用的重要问题。对热成型钢氢脆的影响因素、研究方法、机理和防护方法这4个方面的最新研究进展进行了综述,为相关领域的研究人员提供参考。Enhancing the strength of automotive steels is an effective way to achieve lightweight design of vehicles.However,as the strength of hot-formed steels enhances,their hydrogen embrittlement susceptibility increases accordingly.Hydrogen fracture has become an important problem that hinders the development and application of ultra-high strength hot-formed steels.The latest research progress in four aspects:influencing factors,research methods,mechanisms and protection methods of hydrogen embrittlement of hot-formed steels were reviewed,providing references for researchers in related fields.
