Description

During high speed grinding of transformation toughened ceramics, the applied stress can cause the metastable ZrO2 particles to transform via a martensitic reaction in the near surface region. In this work a constitutive model is proposed that includes transformation plasticity and the effects of the shear components of the transformation due to the grinding process. With the aid of a finite element analysis, the fraction of transformed ZrO2 for a given grinding condition, along with the residual stress, can be predicted. The predictions of the FEM calculation were found to be in good agreement with experimental measurements
