Abstract

The paper focus on possibilities of imaging microstructure changes in high strength low-alloyed carbon steel using an in-situ tensile stage placed in scanning electron microscope (SEM). The sample can be observed either in secondary electrons (SE) or by electron backscattered diffraction (EBSD). We used both types of imaging for different purposes: SE were used mainly for observation of crack initation and propagation and EBSD was used for grain deformations observation. Both methods need different specimen preparation and moreover we used different specimen shapes. All experiments were performed with several TRIP (transformation-induced plasticity) steels containing 0.2 - 0.4 % C, 0.5 - 2 % Si, 0.6 - 1.5 % Mn, 0.03 - 0.06 % Nb.
