本文的目的是开发一种具有最低600 MPa的抗拉强度，结合良好的成形性，扩孔和疲劳强度，通过新的冶金方法，这种应用的钢。该钢已成功地应用于汽车轮盘制造。600 MPa强度的轮盘在动态转弯疲劳和动态径向疲劳试验中表现出更好的耐久性。这种新型钢将是解决先进高强度钢（AHSS）板如双相（DP）钢和相变诱导塑性（TRIP）钢缺乏拉伸凸缘和弯曲能力的解决方案。(c)2012爱思唯尔有限公司版权所有。
The aim of this paper is to develop a steel having tensile strength of 600 MPa minimum combined with good formability, hole expansion and fatigue strength through a new metallurgical approach for such application. The steel, thus developed, has been successfully applied to automotive wheel disc making. Discs made of 600 MPa strength showed improved durability in dynamic cornering fatigue and dynamic radial fatigue test. This novel steel will be a solution to solve the lack of stretch flangeability and bend-ability of advanced high strength steel (AHSS) sheets such as dual phase (DP) and transformation induced plasticity (TRIP) steels.
