【Abstract】 In this paper, the stresses in (Pb1-3/2x+1/2zNdx) (Ti1-y-zMnyInz)O3 (wh-ere x=0.10, y = 0.02, z = 0.06)piezoelectric ceramics have been studied. By analysing and comparing the X-ray diffraction patterns, it was indi-cated that there were stresses present in thin wafer samples. In the expe-riments of stress releasing, we have obtained a feasible way of annealing treatment by which the stresses can be released and the properties of ma-terial can be improved.更多还原
