| Abstract Scope |
Third-generation advanced high strength steels use the deformation-induced phase transformation of austenite to martensite to enhance sheet formability. However, stamping conditions, such as strain rate, strain state, and temperature, influence the balance of strain accommodation via transformation-induced plasticity and dislocation slip. This presentation will explore the processing-property relationships that dictate sheet formability and formed part properties. First, synchrotron diffraction experiments will elucidate the effects of strain rate and temperature on the martensitic transformation. Second, sheet formability experiments, coupled with in-situ measurements of surface strain and temperature evolution, will be used to provide a basis for optimizing microstructures for enhanced formability. |
