Insight into the fracture behaviour and mechanical response of ECAP processed cast and LPBF AlSi10Mg alloy

This project framework gives clear steps for studying how the microstructure, tensile behavior, and fracture of AlSi10Mg alloys change when they are processed by equal‑channel angular pressing (ECAP). It sets up a side‑by‑side comparison of samples made by selective laser melting (SLM/LPBF) and by traditional casting. The plan uses several high‑resolution tools to look at the material’s interior, including optical microscopy, scanning electron microscopy, electron backscatter diffraction, and X‑ray computed tomography (CT) to locate internal defects. To see how the material reacts to load and how cracks grow, the method combines in‑situ tensile CT scanning with loading‑unloading‑reloading (LUR) tensile tests. This lets us measure hetero‑deformation induced (HDI) stresses that come

from the build‑up of geometrically necessary dislocations in the heterogeneous regions. The framework helps researchers model the backward and forward stresses that cause extra work hardening, which explains why LPBF‑processed parts show higher tensile strength and more elongation than cast parts. By offering organized documentation and experimental design steps, this resource supports academic work on deformation heterogeneity and fracture resistance in high‑performance, additively manufactured aluminum alloys.
