Nanosecond timescale plasticity in shock-compressed polycrystalline MgO: evidence for transition in mechanism above 100 GPa
A. Chakraborti, H. Ginestet, F. Bertrand +80
The mechanical properties of ceramics under extreme conditions directly impact applications ranging from shielding spacecrafts, designing plasma facing materials in nuclear fusion…
Volume Collapse Without a Structural Transition in Shock-Compressed FeO
C. Crépisson, T. Stevens, M. Fitzgerald +121
We report x-ray diffraction and emission spectroscopy of FeO under laser-driven shock compression between 31-199 GPa. FeO retains the B1 (rocksalt) structure along the Hugoniot to…
Abrupt crystallization from shock-compressed CaSiO3 glass
A. Amouretti, K. Nonaka, X. Liu +13
We have performed in situ time-resolved X-ray diffraction at ~100 GPa on laser-shocked CaSiO3 glass to investigate the glass-to-crystal transition. At this extreme pressure, we obs…
High Entropy Alloy under Shock Compression: Optical-Pump X-Ray-Probe
Hsin Hui Huang, Meguya Ryu, Shuji Kamegaki +23
High entropy alloys (HEAs) are multi-principal-element alloys designed for tailorable mechanical performance and have been attracting significant engineering interest, yet their fu…
Structural evolution of iron oxides melts at Earth's outer-core pressures
Céline Crépisson, Mila Fitzgerald, Domenic Peake +32
Oxygen and other light elements comprise up to 5 wt% of the Earth's outer-core, and may significantly influence its physical properties and the operation of the geodynamo. Here we…
A Momentum-Resolved X-ray Thomson Scattering Benchmark of Electronic-Response Models in Warm Dense Aluminium
Dmitrii S. Bespalov, Ulf Zastrau, Zhandos A. Moldabekov +58
The robust diagnosis of conditions generated in warm dense matter (WDM) experiments remains a persistent challenge. Here we describe the measurement of shock-compressed aluminium a…
Phase transitions of eutectic high entropy alloy AlCoCrFeNi2.1 under shock compression
Sophie E. Parsons, Kento Katagiri, Hangman Chen +31
High entropy alloys (HEAs) are a new class of metals that exhibit unique mechanical performance. Among HEAs, additively manufactured eutectic high entropy alloys (AM-EHEAs) have re…
Shock-driven amorphization and melt in FeO
Céline Crépisson, Alexis Amouretti, Marion Harmand +28
We present measurements on FeO amorphization and melt under laser-driven shock compression up to 209(10) GPa via time-resolved in situ x-ray diffraction. At 122(3) GPa, a d…
Laser-driven shock compression and equation of state of FeO up to 700 GPa
Alexis Amouretti, Marion Harmand, Bruno Albertazzi +7
We report here the first equation of state measurements of FeO obtained with laser-driven shock compression. The data are in excellent agreement with previous dynamic and s…
Phase transitions of FeO under laser shock compression
A. Amouretti, C. Crépisson, S. Azadi +22
We present in-situ x-ray diffraction and velocity measurements of FeO under laser shock compression at pressures between 38-116 GPa. None of the phases reported by static c…
Resonant inelastic x-ray scattering in warm-dense Fe compounds beyond the SASE FEL resolution limit
Alessandro Forte, Thomas Gawne, Karim K. Alaa El-Din +19
Resonant inelastic x-ray scattering (RIXS) is a widely used spectroscopic technique, providing access to the electronic structure and dynamics of atoms, molecules, and solids. Howe…
Pushing the limits of flow strength in diamond
Anirudh Hari, Kento Katagiri, Wanghui Li +34
Extreme pressures and temperatures create conditions that allow even hard and brittle materials to deform plastically. Despite extensive research, the upper limits of flow strength…
