Predicting and controlling interfacial microstructure of magnesium/aluminum bimetallic structures for improved interfacial bonding

Interfacial Microstructure of Chromium Oxide Coatings

Chromium oxide coatings are chemically inert, have high mechanical strength, hardness and good optical characteristics; therefore, they have been widely used in many applications including corrosion protection, wear resistance, electronics, and optics. Cr2O3 is well suited for wear resistance applications, as it is one of the hardest oxides with 29.5 GPa hardness. Several deposition techniques ...

This paper reviews existing theoretical calculations of the electronic characteristics

A Multi-phase Transition Model for Dislocations with Interfacial Microstructure

We study, by means of Γ-convergence, the asymptotic behavior of a variational model for dislocations moving on a slip plane. The variational problem is a two-dimensional multi-phase transition-type energy given by a nonlocal term and a nonlinear potential which penalizes noninteger values for the components of the phase. In the limit we obtain an anisotropic sharp interfaces model. The relevant...

Interfacial Composition and Microstructure of Fe3O4 Magnetic Tunnel Junctions

Magnetic tunnel junctions with an Fe3O4 top electrode have been fabricated. High resolution transmission electron microscopy (HRTEM) shows that in as-deposited state, Fe and FeO phases exist at the interface. These two phases are believed to have formed as a result of the unstable plasma condition at the start of the Fe3O4 deposition. A relatively low magnetoresistance ratio (MR) (3.5%) and low...
