Weighted ellipse fitting routine for spotty or incomplete Debye-Scherrer rings on a 2D detector
Phani S. Karamched, Yi Xiong, Chi-Toan Nguyen +3
We introduce a weighted ellipse fitting routine to measure Debye Scherrer rings acquired on 2D area detectors and demonstrate its use in strain determination. The method is relativ…

Correlative Synchrotron X-ray Imaging and Diffraction of Directed Energy Deposition Additive Manufacturing
Yunhui Chen, Samuel J. Clark, David M. Collins +10
The governing mechanistic behaviour of Directed Energy Deposition Additive Manufacturing (DED-AM) is revealed by a combined in situ and operando synchrotron X-ray imaging and diffr…
