Abstract
Applied model is based on a description of the dislocation density evolution in metals with hexagonal structure, where forest dislocations and non-dislocations obstacles are considered as obstacles for primary dislocations. Specimens of different orientations between the tensile axis and the rolling direction were deformed in temperature range form 20-300°C at an initial strain rate of 10-3s-1 in order to study the microstructure changes during plastic deformation.
