摘要
提出一种适用于薄膜材料X射线应力分析的试样三维定向模式,在X射线低掠入射的前提下允许按实验所需选择测量方向。高密勒指数晶面衍射和测量方向的合理选择有助于提高测量精度,也利于经典sin2ψ分析法实验线性关系的建立,从而简化了分析和计算程序。
A three-dimensionally oriented mode of experimental specimens was proposed to independently select measuring directions for X-ray stress analyses in thin film materials using low-grazing incidence X-ray diffraction and according to the experimental need. The reasonable selection of diffraction lattice planes with high Miller index and measuring directions would win the favor of enhancing the measuring precision, estahlishing the linear experimental relation for the classical sin^2ψ method and simplifying the procedure of stress analysis and calculation.
