The amalgamation of X-Ray diffraction(XRD) microscopy with grain boundary tracking(GBT) produces a novel method for generating accurate analysis of individual grains during deformation(DAGBT). XRD and GBT are both non-destructive techniques which allow for in-situ characterizing of metals in both an un-deformed state and up to close to fracture. Furthermore, during deformation of the specimen, GBT is able to accesses submicron level analysis of the morphology of the grains in 3-dimensions, allowing for detailed analysis of each grain. Using specially developed algorithms, DAGBT generates accurate information about individual grain orientations utilizing near field

X射线衍射（XRD）显微镜与晶界跟踪（GBT）的融合产生了一种新的方法，用于在变形过程中产生单个晶粒的精确分析（DAGBT）。XRD和GBT都是非破坏性技术，可以在未变形状态和接近断裂状态下对金属进行原位表征。此外，在样品变形期间，GBT能够在3维中访问晶粒形态的亚微米级分析，从而允许对每个晶粒进行详细分析。使用专门开发的算法，DAGBT利用近场产生关于单个晶粒取向的准确信息
