Evolution of Microstrains at Cyclic Incremental Deformation of Steel 42CrMo4
X-ray diffraction line profiles of a ferritic-pearlitic steel at different stages of monotonic and cyclic incremental strain paths were recorded and peak broadening was regarded. Evaluation of integral peak widths shows, that the distortion of structure is strongly dependent on the deformation path. The results for peak broadening at different deformation states correlate with flow stress behaviour and can be explained with certain dislocation arrangements.
