HR-EBSD Measurements near Twins in Zicaloy-2

  • 1. University of Oxford

Description

HR-EBSD measurements made on a Zircaloy-2 sample deformed to 2.7% in tension to generate multiple deformation twins. 
HR-EBSD measurements were made using A Bruker HReFlash detector mounted on a Zeiss Merlin SEM. Sample preparation used Ar ion beam milling on a Gatan PECS II system as a final step. 
The strain, stress and dislocation density variations available here were then calculated using in-house Matlab code (XEBSD).  The work and further analysis of the results is described in

The analysis methods implement in XEBSD are described in the following publications:
