Two Morphologies of Tetragonal Phase in the MgO-PSZ Ceramics

Abstract:

The relationship between microstructures and sintering, heat treatment processes have been investigated in 8mol% MgO-0.5mol% Y₂O₃-PSZ ceramics. The result show that the T phase exhibits two different morphologies during sintering below 1800°C and isothermal holding or aging anew at 1500°C. Their shape, size, distribution and stability all have obvious difference, so they have different effects on the phase transformation toughening.
