| Abstract Scope |
Utilizing 3rd Generation AHSS for structural applications in automobiles offers the promise of lightweighting due to enhanced strength enabling gauge reduction of structural components. However, increasing strength, including yield strength, often comes with commensurate decreases in ductility, formability, and toughness, leading to geometric constraints on part design and limitations in their application. Significant increase in yield strength may be obtained in NanoSteel 3rd Generation AHSS through altered processing of the sheet involving a rolling reduction at intermediate temperatures with the result of maintaining ductility, formability, and toughness. This warm rolling strategy can be applied to either the hot band or cold band condition depending on the targeted applications and end user requirements. In this presentation, the warm rolling effect on structure, properties, and deformation mechanisms of NanoSteel 3rd Generation AHSS will be demonstrated. |
