T. Ebel et al., NUCLEATION IN A CU-0.8AT-PERCENT-CO ALLOY - POLARIZED NEUTRON-SCATTERING INVESTIGATION AND CLUSTERDYNAMICS DESCRIPTION, Journal de physique. IV, 3(C8), 1993, pp. 295-298
By means of polarised small angle neutron scattering it was possible t
o investigate the nucleation period in a Cu-0.8at%Co binary alloy at 4
90-degrees-C. The experimental data show excellent agreement with a co
mputer simulation based on a recently developed clusterdynamic decompo
sition model. From these model calculations the time evolution of the
cluster size distribution and thus of important decomposition paramete
rs such as nucleation rate and mean radius could be derived. Furthermo
re, values for the equilibrium solubility, the interfacial energy and
the diffusivity were extracted.
