Cerium phase transition shock wave
WebFeb 15, 2024 · The identification of the liquid–liquid phase transition (LLPT) in liquids under shock compression is a long-standing challenge. In this Letter, by designing shock-release experiments in shock-driven molten Ce, we observe a first-order LLPT along the release path. The volume change associated with the transition is less than 6%, much smaller … WebCerium has a complex phase diagram that is explained by the presence of structure phase transitions.

WebAs the pressure increases, a multiwave configuration with the participation of isentropic and shock waves is realized in cerium. The initial state in which the shock wave is propagated changes depending on the wave intensity; i.e., the initial state “slides” along the leading isentropic wave.

WebMar 24, 2011 · Cerium has a complex phase diagram that is explained by the presence of structural phase transitions. Experiments to measure the sound velocities in cerium by two methods were carried out to determine the onset of cerium melting on the Hugoniot. WebSep 26, 2011 · Cerium compresses isentropically through the γ - α transition as a result of cerium’s abnormal compressibility in the region of the γ - α transition. The inclusion of the Aptekar-Ponyatovsky model assists in providing a way to handle both the abnormal compressibility and the anomalous melt boundary simultaneously.
WebCerium (Ce) has an atypical phase diagram, presenting, among other things, an isomorphic phase transition between two face centered cubic (fcc) structures a and g. The g-to-a phase transition is believed to be caused by the transfer of valence electrons from the 4f state to the 5d state and induces a volume collapse of ~16% [1,2].
