The object of this investigation is the influence of uniaxial deformation on both the formation of voids and ductile damage in ferritic steel. Specimens are prepared by means of a method which, to a large extent, is free of manipulation and permits the crystal's interior to be observed. These specimens were investigated using a scanning electron microscope (SEM). Anisotropic void formation and growth behaviour were exhibited which is correlated with the material texture using an EBSD investigation. Observing the crystalline structure by means of transmission electron microscopy (TEM) enables the effects of the pore formation and growth to be examined in more detail.
