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)…
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…
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…
