Figure 3
Transmission spectra of weld samples measured at the thermal neutron energies. (a) Steel in both welds, (b) Ti and the weld region (copper filler), (c) Al in two Al–steel welds. The lattice plane indexes (hkl) for certain Bragg edges are marked on the graphs. These Bragg edges are used to quantify the residual strain distribution within the samples. The sudden drop in intensity in the Ti to stainless steel weld area seen in spectrum (b) indicates the substantial presence of large grains in that area of the weld. No strong diffraction features were observed for the Ti area.
