Decoupling Strain-Rate Sensitivity and Deformation Length Scale Effects in Neutron-Irradiated Tungsten: A Coupled Nano-Indentation, HR-EBSD and Crystal Plasticity Study
Prashil S. Joshi, Bethany Jim, Chris Hardie +3
Plastic deformation during strain-rate-controlled spherical nanoindentation is governed by the coupled evolution of constitutive strain-rate sensitivity and deformation length scal…
Calibration and data analysis routines for nanoindentation with spherical tips
Diana Avadanii, Anna Kareer, Lars Hansen +1
Instrumented spherical nanoindentation with a continuous stiffness measurement has gained increased popularity in material science studies in brittle and ductile materials alike. T…
HR-EBSD analysis of in situ stable crack growth at the micron scale
Abdalrhaman Koko, Thorsten H. Becker, Elsiddig Elmukashfi +3
Understanding the local fracture resistance of microstructural features. such as brittle inclusions, coatings, and interfaces at the microscale under complex loading conditions is…
An iterative method for reference pattern selection in high resolution electron backscatter diffraction (HR-EBSD)
Abdalrhaman Koko, Vivian Tong, Angus J. Wilkinson +1
For high (angular) resolution electron backscatter diffraction (HR-EBSD), the selection of a reference diffraction pattern (EBSP0) significantly affects the precision of the calcul…
Macroscopic analysis of time dependent plasticity in Ti alloys
Yi Xiong, Phani S. Karamched, Chi-Toan Nguyen +4
Component failure due to cold dwell fatigue of titanium and its alloys is a long-standing problem which has significant safety and economic implications to the aviation industry. T…
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…
