The microstructure evolution of an aluminum silicon-based alloy after severe plastic deformation processing was examined. An aluminum silicon-based alloy; Al-7wt%Si-2wt%Fe. was processed by the severe plastic deformation technique called high-pressure torsion at room temperature under a high pressure of 6. 0 GPa and rotational speed of 1. https://parisnaturalfoodes.shop/product-category/bronchosan/
