Electron Microscopy Study of Structural Defects Formed in Additively Manufactured AlSi10Mg Alloy Processed by Equal Channel Angular Pressing

This study focused on electron microscopy studies of microstructural defects formed in an additively manufactured (AM) AlSi10Mg alloy as a result post-deformation by equal channel angular pressing (ECAP), with the aim elucidating fundamental deformation mechanisms that govern plasticity both aluminium matrix and silicon phase. article process grain refinement, metastable phase transformations, such stacking faults or amorphous areas severely disrupt face-centred cubic (FCC) crystal lattice symmetry. The findings presented this imply twinning, transformation, amorphization are not mutually exclusive modes Si deformation. Both can occur at ECAP temperature 150 °C. At 100 °C, is dominant mode It was also discovered dislocation slip predominant Al while additionally were within matrix. present provide only understanding micro-mechanism SLMed but open new horizon for development next generation structural materials.
