Abstract
Two limiting cases can be discriminated when solidification processes are considered in which crystallization is involved. With relatively thick samples and high crystallization speeds the process is heat-diffusion controlled, whereas with thin samples and low crystallization speeds the process becomes nucleation-rate controlled. Solidification processes in crystallizable polymers clearly demonstrate the latter type of process. Surprisingly, no mathematical tools had been developed so far for the correct description of the local interplay between heat flow and evolution of heat by crystallization, as controlled by the crystallization kinetics. A review is given of recent developments in this field, which is complicated by the changes in crystallization kinetics, as introduced by the action of shear flow.
