For high strength multiphase steels for structural components in automotive applications many different material properties are required. Therefore a lot of different tests are performed to characterize the material properties during development as a well as optimization of multiphase steels. These tests include classical tensile tests as well as formability tests which characterize bendability, edge crack sensitivity and deep drawability. All these properties are dependent on the microstructure of the material. In the case of high strength multiphase steels microstructure characterization includes evaluation of the volume fraction, stability, grain size as well as the distribution of the different phases present. Possibilities to adjust the microstructure -with regard to reaching the required material properties - are often found in parameters of annealing process of the cold rolled strip. It is shown how microstructural modification for high strength TRIP and dual phase steels resulted in better formability properties and different strength levels.
