Chemical interaction of the In-Ga eutectic with Al and Al-base alloys

The chemical interaction of the indium-gallium eutectic with Al and Al-base alloys is studied by x-ray diffraction, optical microscopy, and electron microscopy. Experimental data are presented that shed light on the reaction mechanism and the diffusion processes responsible for the subsequent disintegration of the material and its dissolution in water. Mechanical tests show that the activation of aluminum leads to a transition from plastic to brittle fracture.
