Understanding high pressure hydrogen with a hierarchical machine-learned potential
Hongxiang Zong, Heather Wiebe, Graeme J. Ackland
The hydrogen phase diagram has a number of unusual features which are generally well reproduced by density functional calculations. Unfortunately, these calculations fail to provid…
Observation of a metastable intermediate during solid-solid phase transformation in response to rapid compression
Michael R. Armstrong, Harry B. Radousky, Ryan A. Austin +23
In order to probe the mechanism of solid-solid phase transformations, we have applied ultrafast shock wave compression (120 picosecond duration) and ultrashort (130 femtosecond) x-…
Long-time behavior of the transition in shocked Zirconium: Interplay of nucleation and plastic deformation
Cristiano Nisoli, Honxiang Zong, Stephen R. Niezgoda +2
We study the thermally activated, slow conversion of the hysteretically retained phase into stable phase in recovered samples of shocked zirconium. The -phase decays in…
