Japanese Patent JP6821419
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an Al-alloy component for joining capable of securing crack resistance during SPR joining.SOLUTION: An Al-alloy component for joining according to the present invention consists of an Al-alloy casting containing 6-12% of Si and comprises a junction that is to be joined mechanically through plastic deformation and a non-junction that is not to be involved in joining. The junction is preferred if greater in primary crystal ratio that is an existence ratio of primary crystal aluminum than the non-junction and a primary crystal ratio that is a ratio of primary crystal ratio in the junction with respect to a primary crystal ratio in the non-junction is 1.2 or greater. Such a junction of an Al-alloy component for joining is obtained by die casting through local application of pressure to a region corresponding to the junction using a pressurization pin when the Al-alloy molten metal poured in the mold becomes a solid-liquid coexistence state due to crystallization of primary crystal aluminum (e.g. at a solid phase rate of 0.25-0.95).SELECTED DRAWING: Figure 1
