On the Mechanism of Aging in Aluminium-Silver Alloys, II. Nature of the Guinier-Preston Zone

抄録

The process of the precipitation from supersaturated solid solution of aluminium containing from 5 to 53 weight % of silver, has been studied by the electrical resistance measurements. The discreteness between the low temperature- and the high temperature-aging has been reconfirmed. The nature of the Guinier-Preston zone, which is the product of the low temperature-aging, has been studied in detail and the correlated phenomena with it, such as the intermediate maximum observed in the isothermal low temperature-aging curve and the reversion phenomenon, have been satisfactorily interpreted in terms of the stability of the Guinier-Preston zone.
