Abstract

Effects of thermal history on spinodal decomposition structure have been investigated using Langer's theory, the cell dynamical system (CDS), model and Monte Carlo (MC) simulation. Even for nonlinear systems, growth of structure with a particular wave-length in the so-called linear manner is caused by the following I operation: Form a structure tosome extent at a higher temperature, and then switch the temperature to a lower value and develop the structure further. We may be able to control the microstructure formed so as to gain a sharp wave-length distribution. Effects of a periodic external field introduced have also been examined using MC simulation. The wave-length of decomposition structure in the metastable state established without the field is an important parameter which allows us to determine the wave-length of the field to be introduced. When the two wave-lengths are of comparable magnitude, control operation is the most successful and the structure israpidly and notably affected even by a relatively weak field.
