Abstract

Thermal mismatch stresses in the ceramic particles of a Cu-ZrW2O8 composite were calculated using a finite-element model, and found to be high enough to trigger a pressure-induced phase transformation, in agreement with previous measurements by X-ray diffraction. The calculated thermal expansion/contraction curves also agree with previous experimental dilatometric results. (C) 2004 Elsevier Ltd. All rights reserved.
