(a) Schematic diagram of the experimental procedure adopted, and (b) the bent bar profile of residual strain calculated using different peaks, and hence crystallographic orientations, in an Al2124 alloy. Note the strain difference between reflections, signifying the presence of intergranular stresses, and also the nature of agreement between the 111 and 222 peak strain. The bold solid line shows the average residual strain profile computed using all peak data weighted with the multiplicity of the corresponding crystal direction. |
