RESUMO
In this paper, the dataset values of the Instrumented Charpy V-notch impact tests (ICITs) of base material (BM), heat affected zone (HAZ) and fusion zone (FZ) of the electron beam welded (EBW) joints of S960M high strength steel (HSS) of the related article have been presented. This dataset provides the force obtained by the ICITs, which can be used to further plot figures and describes the force (F)-displacement (s) graphs of the individual tested samples of the article. The absorbed impact energy measurements in each sample provide information on the material's behaviour under the impact load. The obtained absorbed impact energy indicates the material's toughness and whether the material failure will be ductile or brittle under impact load. The force-displacement curves from axial tensile loading of S960M specimens are presented. The graphs give information about the highest load and behaviour of load-displacement in axial tensile load testing. In addition, the microstructure images of the base material, fusion zone and different heat-affected subzones were taken by the optical microscopic and are the other parts of the data. ICITs data were collected during in situ impact testing of high strength structural steel S960M using Heckert instrumented impact testing equipment connected to a four-channel digital oscilloscope. A more detailed interpretation of the data presented in this article. The presented data are produced as part of the main work entitled "Experimental assessment of microstructure and mechanical properties of electron beam welded S960M high strength structural steel".
RESUMO
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 in situ 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]".
