Figure 1
(a) Side-view schematic of the tensile loading system and experimental geometry. X-rays (thick black line) are incident from the right and a diffracted beam is shown propagating to detector screens on the left at distances L1 and L2 from the ω rotation axis. The sample (box enclosed by Macor) is positioned on this axis. A beamblock (black) attenuates the undiffracted beam but allows passage of upward-directed diffracted beams from the gray sample gauge volume. The load-bearing elements are the Macor ceramic cylinder, the aluminium plate and the vertical standoffs. The entire load stage is mounted on XYZ translation stages which, in turn, are mounted on an air-bearing rotation stage (ω) (Suter et al., 2006BB54). (b) An expanded view of the sample and ceramic holder. Set screws clamp the ends of the wire. The necked sample cross section is imaged on the right via in situ full-field tomography. The arrow indicates the approximate location of a cross section for which detailed analysis is presented.
