Abstract Scope |
The microstructure statistics of two industrially produced advanced high strength quench and partition sheet steels was analyzed by stereology. Planes in the rolling, transverse, and normal direction through the thickness were characterized by both SEM and EBSD. Grain properties, such as size and shape, for different phases, including ferrite, martensite, and retained austenite were quantified. In the intercritically annealed quench and partition steel, the ferrite features were pancaked in comparison to the martensite and retained austenite. In comparison, in the supercritical annealed quench and partition steel, the prior austenite grains were mostly equiaxed. These microstructure statistics were collected with interest of synthetically constructing statistically representative volumes, which can be later used in computational models to predict deformation behaviors. |
