XRD modelling of the FeCr powder ball milled for 64 h measured at the (a) ESRF ID22 beamline [setup (iv)] and (b) ESRF ID31 beamline [setup (iii)]. The dots represent the experimental data, the red line represents the profile modelling, the green (a) and yellow (b) lines correspond to the TDS contribution, grey is the background, and purple is the sum of the TDS and background. (c) CS distribution obtained by WPPM for both setups. (d) Warren plots obtained via the Wilkens model of equation (13[link]) and setup (iv) data. Dashed lines show the initial tangents for the different directions and the corresponding true strain values {ε = 0.0135 [200], 0.0123 [310], 0.0099 [110] and 0.0083 [222]}. The dash–dot lines represent the effective Warren plots obtained via PDF analysis (Section 4.3[link]). Light green corresponds to setup (iii) and dark green to setup (iv).
