Thermodynamic calculations of t to m martenstic transformation of ZrO2–CaO binary system
Source abstract
Abstract
Abstract The phase transformation of different polymorphs in zirconia is very important for the processing and mechanical properties of zirconia ceramics. This paper adopts thermodynamic model which is suitable for ceramic system to calculate the Gibbs free energy change of tetragonal and monoclinic phases in ZrO 2 –CaO binary system. The difference of the Gibbs free energy between tetragonal and monoclinic phases in ZrO 2 –CaO as a function of composition and temperature, namely t → m phase transformation driving force, is thermodynamically calculated from the binary systems. Furthermore, in 8.0 mol% CaO–ZrO 2 , the equilibrium temperature between tetragonal and monoclinic phases, T 0 , was obtained as 1270.3 K, and martensitic transformation starting temperature ( M s ) for t → m transformation of this ceramic with a mean grain size of 2.0 mm was calculated as 805.9 K, which is good agreement with experiment one of 793 K with 12.9 K residual.
