Ductility and Brittle Fracture of Tungsten by Disconnection Pile-up on Twin Boundaries
Omar Hussein, Nicolas Bertin, Jakub Veverka +5
Refractory body-centered cubic (BCC) metals and alloys are of extraordinary importance in modern technological and structural applications. However, their wider adoption in science…
Thermal super-jogs control high-temperature strength in Nb-Mo-Ta-W alloys
Sicong He, Xinran Zhou, Dan Mordehai +1
Refractory multi-element alloys (RMEA) with body-centered cubic (bcc) structure have been the object of much research over the last decade due to their high potential as candidate…
Constriction Percolation Model for Coupled Diffusion-Reaction Corrosion of Zirconium in PWR
Asghar Aryanfar, William A. Goddard, Jaime Marian
Percolation phenomena are pervasive in nature, ranging from capillary flow, crack propagation, ionic transport, fluid permeation, etc. Modeling percolation in highly-branched media…
Monte Carlo modeling of low-energy electron-induced secondary electron emission yields in micro-architected boron nitride surfaces
Hsing-Yin Chang, Andrew Alvarado, Trey Weber +1
Surface erosion and secondary electron emission (SEE) have been identified as the most critical life-limiting factors in channel walls of Hall-effect thrusters for space propulsion…
Monte Carlo Raytracing Method for Calculating Secondary Electron Emission from Micro-Architected Surfaces
Andrew Alvarado, Hsing-Yin Chang, Warren Nadvornick +2
Secondary electron emission (SEE) from inner linings of plasma chambers in electric thrusters for space propulsion can have a disruptive effect on device performance and efficiency…
Structures and transitions in bcc tungsten grain boundaries and their role in the absorption of point defects
Timofey Frolov, Qiang Zhu, Tomas Oppelstrup +2
We use atomistic simulations to investigate grain boundary (GB) phase transitions in el- emental body-centered cubic (bcc) metal tungsten. Motivated by recent modeling study of gra…
