Figure 9
Pole figures of different phases determined by neutron diffraction: (a) the α-Zr phase of the virgin Zr-4 bar and (b) the δ-hydride phase precipitated in the bar. (c) Predicted pole figures of the δ-hydrides formed in the bar, obtained from the experimental ODF of the α-Zr phase in the extruded bar and the δ(111)//α(0001) and δ[]//α[] orientation relationship. The extrusion direction (ED) and tangential direction (TD′) of the bar material are indicated, and the radial direction is in the centre. |
