The paper presents an influence of the Dendrite Arm Spacing click here (DAS) microstructure parameter on the intergranular corrosion of AlSi7Mg aluminum alloy.The samples were subjected to the corrosion process for: 2,5; 12; 24; 48 and 96 hours in NaCl + HCl + H2O solution.It was noted that the DAS parameter significantly influenced on a read more distribution and depth of the intergranular corrosion of the hypoeutectic Al - Si - Mg silumin.
