Figure 13
Comparison of the weld interface position and the diffraction data series for four welds, showing (a) the position of the weld interface relative to the beamline centre and (b) the X-ray diffraction data series labelled for repeat welds. The vertical dashed line in each plot of part (b) represents the intersection of the synchrotron beam centre and the weld interface presented in part (a). Each position curve in part (a) is marked with a cross at the time at which the transformation from ferrite to austenite occurs in the respective series of diffraction data, showing the increasing size of the HAZ during welding. |
