紀要論文
Variations of the Young's modulus and of the internal friction during the aging of the supersaturated solid solution have been examined on polycrystalline specimens of aluminium alloys by the high frequency method at about 13 kilocycles per second ; both the isothermal aging curve and the heating curve have been obtained. The marked difference between the effects of the formation of the Guinier-Preston Zone and the precipitation of the new phase on the Young's modulus has been recognized in Al-Ag alloy, which has been discussed based on the point of view that the formation of the G-P zone is a discrete step in the aging process. In all alloys, it has been confirmed that the Young's modulus increases accompanied by the precipitation of the new phase, but not by the formation of the G-P zone. The effect of aging on the internal friction at room temperature has been found negligible in Al-Ag and Al-Cu alloys, but a certain0 increase has been recognized in Al-Zn alloy. The internal friction versus temperature curves show steep increase at high temperature, which is identical with that in the case of pure aluminium s\
