Abstract
The phase ordering kinetics of an ordered twist grain boundary (TGBA*) liquid crystalline phase from the disordered isotropic melt was investigated experimentally after a temperature quench with respect to quench rate, quench depth and sample geometry. Nucleus growth was followed in situ by polarizing microscopy and image analysis, as spherical germs nucleate and grow, with the germ diameter chosen as a characteristic length L for the growth process. The data are well described by a universal growth law L(t) approximately tn, with a growth exponent n≈1.
