Abstract

We present a computational study on the effects of a uniaxial compression with compression ratio 1/2 on the ordering processes via spinodal decomposition (SD), by numerically integrating the time-dependent Ginzburg-Landau equation. We investigate the pattern growth and two-dimensional structure factors both after a compression in the intermediate stage SD and after a compression in the late stage SD. The results indicate that the compression in the intermediate stage SD causes the phase-separated structure to orient with its interfaces in the direction parallel to the compression axis, and that the compression in the late stage SD causes the phase-separated structure to orient with its interfaces in the direction perpendicular to the compression axis.
