Major influences on the particle-size-transformation-temperature relation in Al2O3-Zr O2 composites
Description
The energetics of martensitic transformation in ZrO2 is studied using a thermodynamic approach, with particular reference to Al2O3--ZrO2 composites. In this paper the different characters of three types of transforamtion-toughened ceramics are analyzed, and several factors affecting the t → m transformation in Al2O3--ZrO2 composites are discussed. The expression of transformation temperature dependence on particle size is derived and has good agreement with experimental results. The energetics concerned with nucleation of martensitic transformation is also discussed
