Abstract:
Low Density Steel (LDS) is known for its excellent corrosion resistance and mechanical properties [1]. LDS has huge potential for commercial applications. The deformation mechanism under different loading conditions remains a topic of ongoing research for LDS. In this study, we aim to gain a comprehensive understanding of the deformation behaviour of LDS at room temperature through wire rolling with a combination of Electron Backscatter Diffraction (EBSD) and Field Emission Scanning Electron Microscopy (FESEM) techniques. FESEM analysis allows us to explore the microstructural features at a higher resolution [2]. By employing dislocation contrast imaging techniques, we examine the dislocation behaviour, dislocation interactions and precipitation. This information helps to elucidate the deformation mechanisms operating at the subgrain and submicron scales [3]. The fraction of High angle grain boundaries, and low angle grain boundaries was found to vary with different rolling reductions. It was evident from EBSD. By combining the EBSD and FESEM results along with fatigue crack growth propagation studies, we propose a comprehensive model for the deformation mechanism in LDS. The model considers the interaction between dislocations, grain boundaries, and other microstructural features, providing a deeper understanding of the plastic deformation processes in this material.
