“…The as-received material is a rolled and annealed Zr702 sheet (containing 1.15 wt-% Hf, 0.07 wt-% Fe, 0.05 wt-% Cr and 0.15 wt-% O) with an equilibrium βtransus temperature of ∼ 990°C (the determination method described in Ref. [20]). Rectangular specimens with dimensions of 11, 9 and 2 mm along rolling, transverse and normal directions (RD, TD and ND), respectively were cut from the as-received sheet.…”

Microstructures and textures of a Zr702 sheet subjected to slow cooling (air cooling (AC) and furnace cooling (FC)) from a near β-transus temperature (980°C) were characterised by electron channelling contrast imaging and electron backscatter diffraction techniques. Results show that textural intensities of both the AC and the FC are markedly higher than that of the initial specimen and the FC specimen owns the strongest texture. After both the heat treatments, the initial bimodal basal textural features are retained with the recrystallisation textural component (0°, 30°, 30°) becoming dominant but the deformation textural component (0°, 30°, 0/60°) largely weakened. The textural intensification is attributed to strong variant selection during the β → α phase transformation and slow cooling-induced sufficient growth of residual prior α grains.

“…Subsequently, the specimens were cooled to room temperature in air and furnace, and denoted as AC and FC specimens, respectively. Cooling rates corresponding to AC and FC were estimated to be ∼ 5 and ∼ 0.02°C/s in a temperature range of 980°C and ∼ 800°C (roughly the α + β region), respectively [20,21].…”
