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…
Correlative Synchrotron X-ray Imaging and Diffraction of Directed Energy Deposition Additive Manufacturing
Yunhui Chen, Samuel J. Clark, David M. Collins +10
The governing mechanistic behaviour of Directed Energy Deposition Additive Manufacturing (DED-AM) is revealed by a combined in situ and operando synchrotron X-ray imaging and diffr…
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…
Spinodal decomposition versus classical gamma-prime nucleation in a nickel-base superalloy powder: An in-situ neutron diffraction and atomic-scale analysis
David M Collins, Neil D'Souza, Chinnapat Panwisawas +4
Contemporary powder-based polycrystalline nickel-base superalloys inherit microstructures and properties that are heavily determined by the thermo-mechanical treatments during proc…
