The Influence of Electron Beam Treatment on Al-Si Alloy Structure Destroyed at High-Cycle Fatigue

Abstract: By scanning and transmission electron diffraction microscopy method the analysis of structure-phase states and defect substructure of silumin subjected to high-intensity electron beam irradiation in various regimes and subsequent fatigue loading up to failure was carried out. It is revealed that the sources of fatigue microcracks are silicon plates of micron and submicron sizes that are not soluble in electron beam processing. The possible reasons of the silumin fatigue life increase under electron-beam treatm… Show more

“…Investigation into the structure of aluminum matrix composites is an important problem to be solved when developing new materials with preset properties [1][2][3][4][5]. Strength characteristics of the above materials greatly depend upon the distribution of strengthening silicon carbide particles.…”
