On the industrial side, selection of materials for a product produced by company must be following function and purpose product. There are many types used various companies in manufacture product, one which is aluminium. This study aims to determine effect temperature variations 3% Al-TiC Composite Heat Treatment 350°C, 450°C, 550°C on mechanical properties microstructure with cooling slope met...

In this study, corrosion behaviour of A356-10 vol.% SiC composites casted by gravity and squeeze casting is evaluated. For this purpose, prepared samples were immersed in HCl solution for 1h at open circuit potential. Tafel polarization and electrochemical impedance spectroscopy (EIS) were carried out to study the corrosion resistance of composites. The Tafel polarization and EIS studies of ...

This paper studies the plastic deformation of a rotating disk made aluminum dispersion-hardened alloys using mechanical tensile tests and structured study optical microscopy methods. Alloys such as AA5056 A356 with dispersed Al3Er TiB2 particles are used initial materials. Tensile strength testing obtained shows that addition in alloy composition leads to an increase its ultimate stress limit (...

In this paper we introduce the SpeakCorrect system which is a Computer Aided Pronunciation Training (CAPT) system for native Arabic students of English. The system is designed with optimized performance for the target users group. It is L1 dependent system and only the frequent pronunciation errors of native Arabic speakers are examined. Several adaptation techniques such as Speaker Adaptive Tr...

Shan-Chen model is a numerical scheme to simulate multiphase fluid flows using Lattice Boltzmann approach. The original ShanChen model suffers from inability to accurately predict behavior of air bubbles interacting in a non-aqueous fluid. In the present study, we extended the Shan-Chen model to take the effect of the attraction-repulsion barriers among bubbles in to account. The proposed model...
