Abstract:
1. A stress-buffering material including a Ca-containing aluminum alloy consisting of: Al, 7.9 to 12 at % of Ca, and unavoidable impurities as an elementary composition, wherein the Ca-containing aluminum alloy includes a first phase of Al and a second phase including Al wherein a volume fraction of the second phase of Al wherein an average size of the second phase of Al wherein when I wherein static Young's modulus of the Ca-containing aluminum alloy is 60 GPa or less, dynamic Young's modulus of the Ca-containing aluminum alloy is 55 GPa or less, and both the static and the dynamic Young's moduli are determined according to Japanese industrial Standards Z 2280:1993 and are measured at room temperature.
