In recent years, there is a high demand for the development of light weight metals in industry. One of the materials is foamed aluminum alloys. In this research, we studied the foaming mechanism for the development of materials using a solidification process.<br> The viscosity in the melt was increased by the oxidation of the melt to form fine Al2O3 particles, and then 1 mass % titanium hydride powder was added to the melt and unidirectionally solidified to make the aluminum alloy foam. Hydrogen bubbles nucleated on the Al2O3 particles at the solid/liquid interface and entrapped in the solid. This shows that the Al2O3 particles not only affect the increase in viscosity but also serve as nucleating agents for the bubbles.
