Article Title: Investigation of the residual strain and deformation mechanisms in laser-welded Eurofer97 steel for fusion reactors

doi: 10.1016/j.msea.2023.145147

Figure Lengend Snippet: Fig. 1. Schematic figures of the experimental setup. (a) In situ neutron diffraction lattice strain measurements and residual lattice strain measurements prior to loading. Inset figure shows the line scans were performed at 300 μm intervals, covering the three sub- regions during uniaxial tension. (b) Lab-based uniaxial tensile ex periments were conducted, and strain evolution was analysed using Vic-2D DIC system. The virtual extensometers (Ext-1-4) are high lighted for macro strain measurements in different regions. (c) In cremental PFIB milling procedures during which residual strain is released. Sequence of secondary electron mages were acquired for residual strain analysis using MATLAB-based DIC method. (d) Nanoindentation experiments were performed using a spherical indenter with 13 cycles of load and unload procedures at the highlighted position in fusion line, HAZ/BM interface, and BM region.

Article Snippet: The post-data treatment was achieved using the MTEX 5.2.8 MATLAB toolbox [25], and the average grain size in the FZ, HAZ, and BM regions was measured from the EBSD orientation maps using the mean linear intercept method [26].
