LOW TEMPERATURE INVESTIGATIONS OF PHASE TRANSFORMATION IN PURE TIN
Original language description
The better understanding of mechanism of phase transformation of white tin to grey tin will helps to protect the historical tin artifacts. The goal of this study is explain some of low temperature phenomena by isothermal measurement of phase transformation in the range 180 - 300 K by X-ray powder diffraction (XRD) and Mössbauer spectroscopy. The phase analysis was focused on the transition of the ß-tin (bct) phase to the a-tin (fcc) phase. Avrami equation was applied to the data for the time dependences of this transition for the constant temperatures, and its parameters were used for the Arrhenius plot. Results derived from data from Mössbauer spectroscopy show a maximum transformation rate at ~200 K. Similarly, XRD data shows the maximum at ~210 K. The difference can be ascribed to changes in the cooling conditions in cryostats in the Mössbauer spectrometer and XRD equipment.
