Outline of Final Research Achievements

Effect of the reduction of the environmental consumption by vacuum free self fusion solidification bonding of aluminum with the periodic motion of the bonding interface was investigated in this study. The reductions of the bonding temperature and the insert metal thickness were introduced by the periodic motion. These reductions realized the energy conservation and the resource saving, respectively. Two types of the deformation mechanism of the bonding interface were classified by the relation with the original surface. The periodic motion during self fusion solidification bonding deformed the bonding interface with the independence from the original shape.
