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…
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…
