Carbon in Cubic and Tetragonal Ferrite
It is generally assumed that the phase diagrams and equilibrium thermodynamic data that apply to the conventional Fe-C system, also are relevant to the case where supersaturated ferrite is in contact with austenite. It seems that this may not be correct, since a change in the symmetry of the ferrite unit cell in the presence of excess carbon has the potential to alter the nature of the phase eq...
متن کاملNucleation barriers for the cubic-to-tetragonal phase transformation
We are interested in the phase transformation from austenite to martensite. This transformation is typically accompanied by the generation and growth of small inclusions of martensite. We consider a model from geometrically linear elasticity with sharp energy penalization for phase boundaries. Focusing on a cubic-to-tetragonal phase transformation, we show that the minimal energy for an inclusi...
متن کاملGarnet: A Rock-Forming Mineral Petrochronometer
Garnet could be the ultimate petrochronometer. Not only can you date it directly (with an accuracy and precision that may surprise some), but it is also a common rock-forming and porphyroblast-forming mineral, with wide ranging—yet thermodynamically well understood— solid solution that provides direct and quantitative petrologic context. While accessory phase petrochronology is based largely up...
متن کاملNucleation barriers at corners for cubic-to-tetragonal phase transformation
We are interested in the energetic cost of a martensitic inclusion of volume V in austenite for the cubic-to-tetragonal phase transformation. In contrast with the work of [Knüpfer, Kohn, Otto: Comm. Pure Appl. Math. 66 (2013), no. 6, 867–904], we consider domain with a corner and obtain a better scaling law for the minimal energy (Emin ∼ min(V , V )). Our predictions are in a good agreement wit...
متن کاملThermotropic cubic and tetragonal phases made of rod-like molecules.
Systematic studies on three dimensionally ordered liquid crystalline phases of different cubic and tetragonal symmetries are presented. The structures of the phases are determined by reconstruction of the electron density distribution from the X-ray diffraction patterns. The known models for electron densities in cubic structures were used whereas a new theoretical model for the structure of th...
