形变诱发马氏体相变是改善含有亚稳残余奥氏体的AHS钢力学性能的一种有效方法。TRIP钢是属于这一组的类别之一。其显微组织由先共析铁素体、贝氏体和亚稳残余奥氏体组成。冷加工使这些钢中的残余奥氏体转变为形变诱发马氏体。其处理路线的技术复杂性是等温保持阶段。在这个阶段，贝氏体形成，残余奥氏体变得稳定，这是该过程的关键方面。对含0.2%碳的CMnSi型低合金钢进行了各种实验性冷却顺序，这些冷却顺序代表了在500 °C至室温的工具温度下进行的压制硬化操作，然后在贝氏体转变区进行等温保持。通过改变冷却参数，可以获得宽范围的含有残余奥氏体的马氏体-贝氏体混合组织，其强度在1300 MPa附近，A20延伸率水平为10%。
Deformation-induced martensitic transformation is used for improving mechanical properties of AHS steels which contain metastable retained austenite. TRIP steels are one of the categories that fall into this group. Their microstructures consist of proeutectoid ferrite, bainite, and metastable retained austenite. Cold working causes retained austenite in these steels to transform to deformation-induced martensite. A technical complication to their treatment routes is the isothermal holding stage. At this stage, bainite forms and retained austenite becomes stabilized which is the key aspect of the process. A CMnSi-type low-alloy steel with 0.2% carbon was subjected to various experimental cooling sequences which represented press hardening operations at tool temperatures ranging from 500 °C to room temperature, followed by isothermal holding in the bainitic transformation region. By varying the cooling parameters, one can obtain a broad range of mixed martensitic-bainitic structures containing retained austenite, with strengths in the vicinity of 1300 MPa, and A20elongation levels of 10%.
