In this paper, we presented the dataset values of full width at half maximum (FWHM) with errors at each point corresponding to the value of longitudinal and transverse residual stress along the three lines for 14 points measured in the EBW welded joints (S960QL and S960M) of the related article [1]. This dataset is used to plot figures and describes their correspondence points with the interrelation of the residual stress graphs (Fig. 4) of the article [1]. The shape of the diffracted peak can be characterised in a simple way by the FWHM, which is the width in degree at half the peak height after background extraction. The measured width consist of instrumental and metallurgical broadening. The variation or increase in FWHM is resulted from the crystalline lattice defect e.g. solute foreign atoms, dislocations and grain boundary. Conversely, if we can determine the physical broadening, we get more information about the structure of the investigated material. In addition, the optical microscopic image of the base materials and weld microstructure are the other parts of the data. Diffraction data were collected using centreless X-ray diffraction (XRD) during residual stress measurement of high strength structural steels S960QL and S960M. A more detailed interpretation of the data presented in this article is provided in article [1]. The presented data are produced as part of the main work entitled "Comparative evaluation of residual stresses in vacuum electron beam welded high strength steel S960QL and S960M butt joints [1]".
在本文中，我们给出了半高宽（FWHM）的数据集值，以及在相关文章[1]中对EBW焊接接头（S960QL和S960M）沿三条线测量的14个点处，对应纵向和横向残余应力值的每个点的误差。该数据集用于绘制图表，并描述它们与文章[1]中残余应力图（图4）的相互关系中的对应点。衍射峰的形状可以通过半高宽以简单的方式表征，半高宽是背景扣除后峰高一半处的角度宽度。测量的宽度包括仪器加宽和冶金加宽。半高宽的变化或增加是由晶格缺陷引起的，例如溶质外来原子、位错和晶界。相反，如果我们能够确定物理加宽，我们就能获得更多关于被研究材料结构的信息。此外，母材和焊缝微观结构的光学显微镜图像是数据的其他部分。在对高强度结构钢S960QL和S960M进行残余应力测量期间，使用无心X射线衍射（XRD）收集衍射数据。文章[1]中提供了对本文所呈现数据的更详细解释。所呈现的数据是作为题为“真空电子束焊接高强度钢S960QL和S960M对接接头残余应力的比较评估[1]”的主要工作的一部分产生的。
