Phase stability and elastic properties of Cr–V alloys

Phase stability and elastic properties of Cr-V alloys.

V is the only element in the periodic table that forms a complete solid solution with Cr and thus is particularly important in alloying strategy to ductilize Cr. This study combines first-principles density functional theory calculations and experiments to investigate the phase stability and elastic properties of Cr-V binary alloys. The cluster expansion study reveals the formation of various ...

Phase Boundaries in Alloys with Elastic Misst

We study a mathematical model describing phase transformations in alloys with kinetics driven by mass transport and stress. To describe the dynamics, a Cahn-Hilliard system taking elastic eeects into account is studied. Existence and uniqueness results for the resulting singular elliptic{parabolic system are given. In the Cahn-Hilliard model, phase boundaries are described by a diffuse interfac...

Stability and elastic properties of hydrogen-loaded Ti1-xAlx alloys: An ab initio study.

some properties of fuzzy hilbert spaces and norm of operators

in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...

Elastic Properties and Stability of Physisorbed Graphene

Graphene is an ultimate membrane that mixes both flexibility and mechanical strength, together with many other remarkable properties. A good knowledge of the elastic properties of graphene is prerequisite to any practical application of it in nanoscopic devices. Although this two-dimensional material is only one atom thick, continuous-medium elasticity can be applied as long as the deformations...
