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…
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…
