Thermal stability and thermal expansion behaviour of ZrO2/Y2O3 multilayers deposited by pulsed laser deposition technique

The Effect of ZrO2 Nanoparticles on the Microstructure and Properties of Sintered WC–Bronze-Based Diamond Composites

“…In addition, the mismatch in the coefficient of thermal expansion (CTE) between metal matrix (bronze > 18 × 10 −6 K −1 , WC ~6 × 10 −6 K −1 ) and ZrO 2 (~10 × 10 −6 K −1 ) should be taken into further consideration [23,26,27]. During the cooling from the processing temperature (980 °C), thermal stresses around nano-ZrO 2 particles cause plastic deformation stresses that reduce quickly as distance from the interface increases, this generating dislocation defects in the close vicinity of nano-ZrO 2 [19].…”
