Insights into hydrogen-induced vacancy stability and creep in chemically complex alloys
Prashant Singh, Yash Pachaury, Aaron Anthony Kohnert +2
Hydrogen (H) content modifies the creep response of Fe-based alloys by altering thermodynamics of point-defects; here we identify the electronic-structure mechanism underlying this…

Effect of Anisotropic Peierls Barrier on the Evolution of Discrete Dislocation Networks in Ni
John D. Shimanek, Darshan Bamney, Laurent Capolungo +2
Over low and intermediate strain rates, plasticity in face centered cubic (FCC) metals is governed by the glide of dislocations, which manifest as complex networks that evolve with…
