Assessment of Density and Character of Dislocations in Cyclic Loaded Stainless Steel Using X-ray Diffraction Profile Analysis

摘要: Asymmetric stress-controlled fatigue i.e., ratcheting behaviour of a non-conventional stainless steel X12CrMnNiN17-7-5 has been investigated with varying mean stresses, stress amplitudes and number cycles at room temperature using servo hydraulic universal testing machine. The X-ray diffraction profile analysis the modified Williamson–Hall equation carried out in order to estimate dislocation densities specimens subjected deformation. Increase strain accumulation explained by increase ratcheted correlation between produced deformation estimated density established.
