Thermal Hysteresis of Mesoscopic Phase Transitions in Fluid and Solid Metals: Critical Point and Global Diagram of Tantalum

Thermal hysteresis of mesoscopic phase transitions in fluid metals: From tantalum to aluminum and gold with their critical points and non-mean-field global diagrams

“…Unfortunately, this outstanding scientist past away recently. The performed in Section 4 comparative analysis of FT-calibration applied to Ta [1] and to Al here demonstrates the promising predictive capability of CVL-diagram for the explanation of mhd-instability. The specific peculiarities of the proposed FT-calibration is described in Section 4 in the context of comparative investigation of the binding and cohesive energies.…”

“…Both end-points of a reference Eq. ( 1) from the work [1], belong to the imaginable straight line identified with the scaling FT-model's 0 P  isobar. It can be obtained by the extrapolation to both axes   0, 0 T   of the relatively short linear l-segment.…”

“…This quantity corresponds to the differential Joule-Lentz's heat in Eq. ( 36) from [1]. The natural consequence of both equivalent Horstamann's and Clausius' expressions of the Second Law was used for the concept of IEX-irreversibility introduction.…”

“…TT  for liquids is always located above or nearly to the high temperatures of normal boiling point   0 , bl TP  for many metals [9]. The proposed option of congruent CVL-predictions [1][2][3][4][5][6] is realizable just in the respective long "low-temperature" interval for sub-atmospheric vapor pressures:   0 vb P T T P  = .…”

“…This work follows the study of the non-mean-field congruent vapor-liquid (CVL) phase diagram for Ta in [1], where the FT-predictive scheme was described in detail. Thus, now we will refer to some equations of it to avoid the unnecessary repetition, while the basic FT-correlations for the current work will be considered directly in the context.…”
