由于其热冲压后的上级机械性能，USIBOR 1500 P在汽车结构（保险杠、车门、白色车身）的防侵入应用中增长非常迅速。由于坯料在高温下冲压（通常在600°C至800°C之间），然后立即在封闭的成型模具中淬火，因此可以实现1500 MPa的极高强度水平，而不会出现形状偏差或回弹，并且适用于非常复杂的形状。这种性能目前无法与任何其他冷冲压材料相匹配。本文简要介绍了USIBOR 1500 P的应用现状，重点介绍了其冲压行为的有限元模拟热机械模型。将介绍和讨论当前关于材料本身、加工及其在定制机械性能方面提供的机会的创新趋势。
Thanks to its superior mechanical properties after hot stamping, USIBOR 1500 P experiences a very rapid growth in anti‐intrusion applications of automotive structures (bumpers, doors, bodies‐in‐white). As the blank is stamped at high temperature (typically between 600°C and 800°C) and then immediately quenched in the closed forming die, the very high strength level of 1500 MPa can be achieved without shape deviation or springback, and for very complex shapes. This performance cannot currently be matched by any other cold stamped material. This paper intends to give a short overview of the current status in application of USIBOR 1500 P, with a specific focus on the thermomechanical modelling of its stamping behaviour in finite element simulation. Current innovation trends with respect to the material itself, its processing and the opportunities it offers in terms of tailored mechanical properties will be presented and discussed.
