摘要
The kinetics of nucleation and growth in the first-order transition belonging to the one-dimensional nonconserved-order-parameter system has been studied by time-resolved synchrotron x-ray diffraction measurements of the stacking transition in stage 1 rubidium-graphite intercalation compounds. The volume of growing phase can be scaled by the theoretical function of Avrami. The line shape is scaled by a squared Lorentzian which is consistent with a recent theory. The nuclear size has a nearly logarithmic time dependence which is in contrast to the linear time dependence in the usual theories. © 1990 The American Physical Society.
