进行了一项可行性研究，以显示能量色散X射线衍射（EDXRD）测量厚工业材料中的三维应变分布的能力。使用高达130 keV的光子能量来保证穿透样品，并将曲线拟合技术应用于峰位置测定。该系统用于测量穿过9.5mm厚的悬臂钢筋的厚度的应变梯度。
A feasibility study was performed to show the ability of energy dispersive x-ray diffraction (EDXRD) to measure three dimensional strain distributions in thick industrial materials. Photon energies up to 130 keV were used to guarantee penetration through the sample and curve fitting techniques applied to peak position determination. This system was used to measure the strain gradient through the thickness of a 9.5 mm thick cantilevered steel bar.
