Abstract

The transformation kinetics of βSn (white tin) to and from Sn (grey tin) are studied by synchrotron X-ray diffraction of seeded powder samples of 99.99% Sn. An analysis of thermal expansion behaviour revealed that the volume change of transformation increases as the temperature decreases. The βSn → Sn transformation was well described by Johnson-Mehl-Avrami kinetics with an Avrami exponent of 3, which was confirmed to be due to three-dimesional growth from pre-existing nuclei by a microstructural study. The Sn → βSn transformation exhibited a decreasing Avrami exponent from ∼4 to ∼1 during the transformation. Time-Temperature-Transformation curves are plotted from the isothermal transformation data and are compared with past work.
