Neutron-scattering study reveals a dynamical scaling crossover during phase separation in an iron-chromium alloy, indicating a late-stage transition from coagulation to condensation.
A neutron-scattering study of phase separation in the Fe-Cr alloy system clearly indicates dynamical scaling. The results are compared with the predictions of recent scaling theories. Both the time evolution of the characteristic wave vector and the scaling function of the structure factor show crossover phenomenon. The crossover is attributed to a transition from a coagulation to a condensation process at a late stage of phase separation in alloy systems.
