Abstract
By means of polarised small angle neutron scattering it was possible to investigate the nucleation period in a Cu-0.8at%Co binary alloy at 490°C. The experimental data show excellent agreement with a computer simulation based on a recently developed clusterdynamic decomposition model. From these model calculations the time evolution of the cluster size distribution and thus of important decomposition parameters such as nucleation rate and mean radius could be derived. Furthermore, values for the equilibrium solubility, the interfacial energy and the diffusivity were extracted.
