Abstract: The purpose of this work was to study chemical interaction of the In-Ga eutectic with Al and Al-based alloys. A number of physicochemical characterization techniques were used with the aim of gaining information about the mechanism of this interaction and the processes responsible for the subsequent disintegration of the material and its dissolution in water with the formation of pure hydrogen. Subsequent grain-boundary and volume diffusion of liquid In–Ga mixture into aluminum or its alloys gives rise to the embrittlement of the material and drastically increases its reactivity relative to water. We carried out tensile strength tests on aluminum plates. Specimens that were not activated with liquid In–Ga mixture revealed a well-defined plastic zone. The plastic strain of activated aluminum was substantially lower. The tensile strength of aluminum as a function of activation temperature was also examined.
