Abstract
The formation and development of voids in both the single-phase ferritic steel DC04 and the dual-phase ferritic-martensitic steel DP600 are discussed. Various mechanisms and kinetics of void formation are considered regarding the influence of dislocation glide, precipitates and other parameters. Different characteristic locations in the microstructure are investigated at which strain concentrations during plastic deformation can occur and cause the formation of voids and microcracks. For the specimen preparation ion slope cutting is applied. Voids and cracks revealing ductile damage are analyzed by Scanning Electron Microscopy (SEM). Stress concentrations in consequence of plastic deformation could be shown by extinction contours on images recorded by Transmission Electron Microscopy (TEM).
