Microstructure of Diffusion-Bonded Mg-Ag-Al Multilayer Composite Materials

Microstructure and optical properties of Ag/ITO/Ag multilayer films

Transflective and highly conductive Ag/ITO/Ag multilayer films were prepared by magnetron sputtering on glass substrates. The microstructure and optical properties of Ag/ITO/Ag multilayer films were systematically investigated by X-ray diffraction, scanning electron microscopy, and ultraviolet-visible spectroscopy. The optical properties of the multilayer films were significantly influenced by ...

ix Czech Technical University in PragueKlokner InstituteAbstract Analysis of Composite Materials with Random Microstructureby Jan Zeman In this thesis, a comprehensive approach to the modelling of composite materials witha microstructure exhibiting various types of disorder is proposed. In particular, a fibrousgraphite-epoxy composites with fibers randomly distributed wi...

Microstructure Modelling of Hot Deformation of Al-1%Mg Alloy

This study presents the application of the finite element method and intelligent systems techniques to the prediction of microstructural mapping for aluminium alloys. Here, the material within each finite element is defined using a hybrid model. The hybrid model is based on neuro-fuzzy and physically based components and it has been combined with the finite element technique. The model simulate...

Clustering and Segregation of Mg and Ag Atoms during the Precipitation Processes in Al(-Li)-Cu-Mg-Ag Alloys

This paper reports three dimensional atom probe (3DAP) results of solute clusters and precipitates in early aging stages of Al-Cu(-Li) alloys containing small amounts of Ag and Mg atoms. In an as-quenched Al-1.9Cu-0.3Mg-0.2Ag (at.%) alloy, solute atoms are uniformly dissolved. On aging for 5 s at 180°C, Ag and Mg atoms form co-clusters. These co-clusters do not have well defined shape, but they...
