Homogenization of one phase flow in a highly heterogeneous porous medium including a thin layer

In this work we consider a model problem describing one phase flow through a thin porous layer made of weakly permeable porous blocks separated by thin fissures. The flow is modeled by a linear parabolic equation considered in a bounded 2D domain with high contrast coefficients. The problem involves three small parameters: the first one characterizes the periodicity of the distribution of the b...

DENSIFICATION AND MICROSTRUCTURE CHARACTERISTICS OF A PREALLOYED ALPHA BRASS POWDER PROCESSED BY LIQUID PHASE SINTERING

The rapidly solidified prealloyed alpha brass powder with a size range of 40 to 100 μm produced by water atomization process was consolidated using liquid phase sintering process. The relationships between sintering temperature, physic-mechanical properties and microstructural characteristics were investigated. Maximum densification was obtained at 930 °C, under 600 MPa compacting pressure,...

تشکیل ترکیب بین‌فلزی Al3Ti در فصل مشترک اتصال زوج نفوذی آلومینیوم- تیتانیم از طریق انجام عملیات حرارتی نفوذی

In this study, the formation of the Al3Ti intermetallic compound at the junction interface of aluminum-titanium was investigated during deposition and annealing. The results illustrated that during the deposition process, one thin layer of Ti3Al2 intermetallic compound was created at the junction interface. During the annealing at 550 °C, this layer was transformed to the  Al3Ti interm...

Annealing temperature effect on nanostructure and phase transition of Copper Oxide thin films

This paper addresses the annealing temperature effect on nanostructure and phase transition of copper oxide thin films, deposited by PVD method on glass substrate (at 110 nm thickness) and post annealed at different temperatures (200-400°C) with a flow of 1 cm3s-1 Oxygen. The X-ray diffraction (XRD) was employed for crystallographic and phase analyses, while atomic force m...
