Anisotropy of losses in grain-oriented Fe–Si

Thermal conductivity anisotropy and grain structure in Ge2Sb2Te5 films

Although lateral thermal conduction in Ge2Sb2Te5 (GST) films can influence the performance of phase change memory (PCM), there are no data available for the in-plane thermal conductivity. This work measures both the in-plane and the out-of-plane thermal conductivities for the amorphous, face-centered-cubic, and hexagonal-close-packed phases of GST using two independent techniques. For crystalli...

Comparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester

 Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...

Sensitivity of Texture Development during Grain Growth to Anisotropy of Grain Boundary Properties

Anisotropy of Segregation at Grain Boundaries and Surfaces

The purpose of this article is to review analytical models of the anisotropy of segregation to grain boundaries (GBs) and surfaces, and to evaluate their predictions. A summary of Gibbsian interfacial thermodynamics is provided as an introduction to the topic. This is followed by a historical overview of previous analytical models. A recently developed model of the dependence of GB segregation ...

Effect of texture and grain shape on anisotropy

An attempt is made to summarize the different ways of modelling the anisotropy of a polycrystalline material. At the single crystal level, the formulation based on Schmid law or viscoplasticity shows clearly the microscopic anisotropy due to the hardening and the orientation changes. It is also shown how viscoplasticity leads to a unique slip system activity irrespectively of the rate sensitivi...
