利用中子飞行时间衍射技术对Pb（Zr，Ti）O3和PZT基多晶电瓷进行了原位单轴压缩实验。弹性晶格应变和织构演化观察到PZT的近边缘的准同型相界（与四面体和菱面体相存在）。多相Rietveld分析产生了各向异性的晶格应变演化曲线在平行和垂直于加载轴的两个阶段的方向。通过应用March-Dollase织构模型，定量分析了外加应力下的畴变。
In situ uniaxial compression experiments on Pb(Zr,Ti)O3 or PZT-based polycrystalline electroceramics were conducted using time-of-flight neutron diffraction. Elastic lattice strain and texture evolution were observed in PZT’s near the edge of the morphotropic phase boundary (with tetragonal and rhombohedral phases present). Multiphase Rietveld analysis yielded anisotropic lattice strain evolution curves in directions parallel and perpendicular to the loading axis for both phases. A quantitative analysis of the domain switching under applied stress was possible through application of a March–Dollase model for texture.
