Abstract

The time evolution of the structure function and of the cluster (or grain) distribution following quenching in a model binary alloy with a small concentration of minority atoms is obtained from computer simulations. The structure function S¯(k,t) obeys a simple scaling relation, S¯(k,t)=K3F(kK) with K(t)ta, a0.25, during the latter and larger part of the evolution. During the same period, the mean cluster size grows approximately linearly with time.
