Abstract

In situ high temperature synchrotron X-ray diffraction was employed to shed light on the kinetics and mechanisms behind the transformation between the orthorhombic and hexagonal phase in Dy₂TiO₅. The thermal expansion behavior was examined to bring additional clarity and understanding of the mechanism at the transition temperature. The transformation was found to be reconstructive and first ordered in nature, and fit well with the JMAK nucleation and growth kinetic model, with an Avrami exponent of 1.66 and activation energy of 267 kJ/mol.
