抄録
Effects of 0.1at% Cr, Zr, Fe, V, Ag, Be, Cd, In, Si, Ge, Sn and 0.01∼0.5 at% Cu on aging characteristics of Al-9at% Mg alloy have been studied by measurements of electrical resistivity and hardness and electron microscope observations.<BR>The rate of clustering in Al-9at% Mg alloy is remarkably decreased by the addition of more than 0.03 at% Cu. In the Cu-bearing alloys two kinds of clusters exist : one is composed of Mg and Al atoms and the other includes Cu atoms. The latter exists even above 100°C, at which the former is easily dissolved.<BR>Transition elements such as Cr, Zr, Fe and V retard slightly the clustering, but accelerate precipitation at higher temperatures.<BR>The effects of Ag, Be, Cd and In on aging kinetics are also similar to the case of those transition elements, except that these elements prevent the formation of precipitate-free zones and produce a finer dispersion of precipitates.<BR>It seems that Si, Ge and Sn have no trace-element effect on the clustering and the precipitation in Al-9at% Mg alloy.
