Charge redistribution at metal-ZrO2 interfaces: A combined DFT and continuum electrostatic study
Ximeng Wang, Yongfeng Zhang, Dmitry Skachkov +5
Nanoscale metallic inclusions (NMIs) are commonly observed within oxide scales formed during high-temperature oxidation, revealing the existence of chemical and electronic heteroge…
Mapping optical, chemical, structural features in ZrO2 via cross-sectional SEM-Cathodoluminescence correlation microscopy
Ricardo Vidrio, Yuhan Tong, Junliang Liu +11
Understanding how nanoscale heterogeneities influence charge transport and mass transfer in oxides is critical for developing advanced materials for energy and electronic uses. In…
Elastic Strain Associated with Irradiation-Induced Defects in Self-ion Irradiated Tungsten
Guanze He, Hongbing Yu, Phani Karamched +2
Elastic interactions play an important role in controlling irradiation damage evolution, but remain largely unexplored experimentally. Using transmission electron microscopy (TEM)…
Using local GND density to study SCC initiation
Naganand Saravanan, Phani S Karamched, Junliang Liu +3
In this work, strain and geometric necessary dislocations (GNDs) have been mapped with nm-resolution around grain boundaries affected by stress corrosion cracking (SCC) or intergra…
Non-destructive study of collision cascade damage in self-ion irradiated tungsten using HR-EBSD and ECCI
Hongbing Yu, Phani Karamched, Suchandrima Das +3
Understanding defect production and evolution under irradiation is a long-standing multi-scale problem. Conventionally, experimental examination of irradiation-induced defects (IID…
Grain Boundary Serration in Nickel Alloy Inconel 600: Quantification and Mechanisms
Yuanbo T. Tang, Phani Karamched, Junliang Liu +3
The serration of grain boundaries in Inconel 600 caused by heat treatment is studied systematically. A new method based on Fourier transforms is used to analyse the multiple wave-l…
Surface terraces in pure tungsten formed by high-temperature oxidation
Hongbing Yu, Suchandrima Das, Junliang Liu +2
We observe large-scale surface terraces in tungsten oxidised at high temperature and in high vacuum. Their formation is highly dependent on crystal orientation, with only {111} gra…
Forescattered electron imaging of nanoparticles in a scanning electron microscopy
Junliang Liu, Sergio Lozano-Perez, Phani Karamched +3
In this study, we have used a Zr-Nb alloy containing well-defined nano-precipitates as a model material in which to study imaging contrast inversions (atomic number or diffraction…
On the depth resolution of transmission Kikuchi diffraction (TKD) analysis
Junliang Liu, Sergio Lozano-Perez, Angus J. Wilkinson +1
In this paper, we have analysed the depth resolution that can be achieved by on-axis transmission Kikuchi diffraction (TKD) using a Zr-Nb alloy. The results indicate that the signa…
Mapping the full lattice strain tensor of a single dislocation by High Angular Resolution Transmission Kikuchi Diffraction (HR-TKD)
Hongbing Yu, Junliang Liu, Phani Karamched +2
The full lattice strain tensor and lattice rotations induced by a dislocation in pure tungsten were mapped using high-resolution transmission Kikuchi diffraction (HR-TKD) in a SEM.…
