An in-situ synchrotron diffraction study of stress relaxation in titanium: Effect of temperature and oxygen on cold dwell fatigue
Yi Xiong, Phani S. Karamched, Chi-Toan Nguyen +5
There is a long-standing technological problem in which a stress dwell during cyclic loading at room temperature in Ti causes a significant fatigue life reduction. It is thought th…
Ultra high-temperature deformation in a single crystal superalloy: Meso-scale process simulation and micro-mechanisms
Yuanbo T. Tang, Neil D'Souza, Bryan Roebuck +3
A mesoscale study of a single crystal nickel-base superalloy subjected to an industrially relevant process simulation has revealed the complex interplay between microstructural dev…
Orientation dependence of the nano-indentation behaviour of pure tungsten
Hongbing Yu, Suchandrima Das, Haiyang Yu +3
Coupling of nano-indentation and crystal plasticity finite element (CPFE) simulations is widely used to quantitatively probe the small-scale mechanical behaviour of materials. Earl…
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…
Cold Creep of Titanium: Analysis of stress relaxation using synchrotron diffraction and crystal plasticity simulations
Yi Xiong, Phani Karamched, Chi-Toan Nguyen +4
There is a long standing technological problem in which a stress dwell during cyclic loading at room temperature in Ti causes a significant fatigue life reduction. It is thought th…
