Abstrakt: We study the effect of gallium-containing aqueous solutions on polycrystalline aluminum. The procedure for kinetic studies of the selected system is described. It is found that in the reaction of polycrystalline aluminum with gallium-containing aqueous solutions, gallium penetrates along the aluminum grain boundaries, which, upon the application of external stress, leads to failure of the sample. It is found that gallium can penetrate along the aluminum grain boundaries both in the liquid and solid state; the rates of penetration of gallium in the liquid and solid states are determined.
