Figure 8
Experimental pole figures of different phases determined by neutron diffraction: (a) the α-Zr phase of the virgin Zr-4 plate (Wang et al., 2013

) and (b) the δ-hydride phase precipitated in the plate. (c) Predicted pole figures of the δ-hydrides formed in the plate, obtained by applying the δ(111)//α(0001) and δ[ $[1{\overline 1}0]$ ]//α[ $[11{\overline 2}0]$ ] orientation relationship to the ODF of the α-Zr phase in the plate. The plate-rolling direction (RD) and transverse direction (TD) are indicated, and the normal direction (ND) is in the centre.
