The applicability of Johnson-Mehl-Avrami model in the thermal analysis of the crystallization kinetics of glasses☆
TL;DR: In this paper, the applicability of the Johnson-Mehl-Avrami equation for non-isothermal crystallization kinetics has been investigated, and it has been shown that it has limited applicability for the nonisothermal transformations involving nucleation and growth.

TL;DR: In this article, the steady state velocity of a planar interface and the chemical composition of the growing phase in terms of the interface temperature and the composition of parent phase at the interface are predicted.

Phase Transformations in Solids
C. N. R. Rao,K. J. Rao +1 more
TL;DR: A brief account of various types of crystal structure transformations will be presented in this chapter as discussed by the authors, and some aspects of interest to chemists have been reviewed by Ubbelohde1, Rao and Rao2 and Smoluchowski3.

A unified approach to motion of grain boundaries, relative tangential translation along grain boundaries, and grain rotation
John W. Cahn,Jean E. Taylor +1 more
TL;DR: In this article, the authors postulate that almost any motion of an interface between two crystals can produce a coupled tangential motion of the two crystals relative to each other which is proportional to the normal motion.
