Stability of A15 type phases [PDF]
Solid State Communications, 1974 Abstract Previous works dealing with the stability of the A15 phases are reviewed. Data for over 60 known A15 phases are used to develop criteria for stability which may be applied to hypothetical A15 phases. Occurrence of these phases is examined in terms of the valence bond concepts of the Engel-Brewer correlation and in its frequency with changes ...

Insight into the FCC→HCP Transformation in Co-Rich Co-Cr-Fe-Mn-Ni High-Entropy Alloys
Metals, 2023 The existence of an HCP phase in FCC-type high-entropy alloys can improve the alloy’s mechanical properties. In many cases, an HCP phase is induced by deformation.

Island Stability in Phase Space [PDF]
Journal of Physics: Conference Series, 2018 Starting with a conventional bump on tail problem, which is equivalent to finding a solution of the Vlasov/Fokker-Planck equation in the presence of the phase space island, we obtain a primary equilibrium state. The stability of this state is investigated as a function of the effective velocity-space drag and diffusion, as well as the width of these ...

Phase stabilities at a glance: Stability diagrams of nickel dipnictides [PDF]
The Journal of Chemical Physics, 2013 In the course of the recent advances in chemical structure prediction, a straightforward type of diagram to evaluate phase stabilities is presented based on an expedient example. Crystal structures and energetic stabilities of dipnictides NiPn2 (Pn = N, P, As, Sb, Bi) are systematically investigated by first principles calculations within the framework

Inhibiting octahedral tilting for stable CsPbI2Br solar cells
InfoMat, 2022 The intrinsic phase instability of CsPbI2Br perovskite hinders its development and application in solar cells. Herein, we adopt 1‐butyl‐3‐methylimidazolium hexafluorophosphate (BMIMPF6), a hydrophobic ionic liquid (IL), to improve the phase stability of ...
