Abstract: The reinforcement particles play important roles in determining microstructural development and properties of Al6061 composites. In the present work, the aging behavior of Al6061 reinforced with Y2O3 and TiC particles produced via mechanical alloying are investigated. The results indicate that the peak-aged Al6061 alloy without reinforcement demonstrates the highest hardness, which co...

The failure of an AL6061-T6 and Kevlar-29 composite plate under high-velocity impact from an S-S (structural Steel) projectile tool was investigated using the nonlinear explicit finite element software, ANSYS AUTODYAN. Two velocity ranges 350 m/s and 700 m/s were used for FEM simulation. It was analyzed that AL6061-T6 is more resistant than KELVAR 29 at both ranges but Kevlar 29 is light in wei...

C. Rontescu, T. D. Cicic, C. G. Amza, O. Chivu, Polytechnic University of Bucharest, Romania. D. Dobrotă, Engineering Faculty, University “Constantin Brâncuşi” of Târgu-Jiu, România This paper presents the results obtained following the Finite Element Method (FEM) simulations on a bike frame made of 3 different materials, Al6061, Carbon Fiber and Ti6Al4V, in order to identify the optimum materi...

Since composite materials were initially used in airplanes a few decades ago, substantial research has been done on problems such as lightning strike protection (LSP) and electromagnetic interference (EMI) shielding. In the current state of technology, aerospace industry needs cutting-edge to meet requirements like lower weight higher values strength stiffness protect against interference. On o...

In this research work, estimation of tool wear for the CBN / PCD tool has been done by using Echostate Neural network during machining of Al6061 metal matrix composite. AN estimation percentage of 90.62% has been achieved.

This study presents the design and stress analysis of mobile robot switchover module (track tensioner), which helps the robot to work in hybrid locomotion mechanism. The track tensioner is a loading and unloading module that helps the locomotion system transformability while robot moves either on wheel or track mechanism. The selection of suitable material for its design, the model is therefore...

Microstructural inhomogeneity generally deteriorates the corrosion resistance of materials due to the galvanic effect and interfacial issues. However, the situation may change for nanostructured materials. This article reports our studies on the corrosion behavior of SiC nanoparticle-reinforced Al6061 matrix composite. It was observed that the corrosion resistance of Al6061 increased when SiC n...

The high cost of fabrication hindered the actual application of metal matrix composite (MMC) despite of their high stiffness, strength, corrosion resistance, wear resistance, non-reactivity with chemicals and so many other tailored quality which are never obtained in alloy of metals. In this study, a modest attempt has been made to find out the process parameters at which best mechanical proper...

Nowadays, fly-wire is only used for flying-related things. All plane controls depend on electronics, but they also must deal with high-intensity radiated fields. This equipment might need an electromagnetic shield to protect it from outside pollution. The current work aims develop a mesh around the operating and make better. AL6061 was create metal matrix composite. Here three combinations of M...

In the present study the effect of phase volume fraction on the reinforcement of microstructure and tensile properties of composite extrusion process Al6061/SiC has been studied. For this purpose, the base alloy Al6061 using pure aluminum ingots, silicon, of Al-50% Mg, Al-10% Cr and a thin copper rod was prepared. Next, the composite Al6061/5% SiC, Al6061/10% SiC, Al6061/15% SiC and Al6061/20% ...
