摘要
Mg-PSZ(magnesia-partially-stabilized zirconia)has been studied under compressive loading at room temperature.Mechanical strain was recorded continuously using strain gauges while the sample phase composition and microstructure has been recorded at regular intervals on the ENGIN-X pulsed-neutron facility at the Rutherford-Appleton Laboratory in Didcot,England.Diffraction pattern analysis has been accomplished using the GSAS II software.The observed mechanical strain is time dependent,and a correlation is established between the mechanical creep strain and the phase and microstructural changes observed.Deformation and associated microstructural changes have been observed for all applied loads but were most marked for the highest load which was-1,200 MPa.It is suggested that the ongoing deformation and microstructural changes after unloading the specimen,are on account of a stress within the sample.
