Abstract

Experimental data show that the coefficient of diffusion of Zn in an Al matrix is a linear function of Zn concentration. The presence of Mg in Al-Zn alloys accelerates Zn diffusion. The presence of small amounts of Fe has no significant effect. The bonding of two Zn atoms to Al is stronger than that of the Zn plus Mg pair. It is possible, therefore, that the clustering of Zn atoms precedes the formation of Guinier-Preston zones in ternary alloys.
