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...

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...

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...

Hot deformation behavior of a medium Cr/Mn Al6061 aluminum alloy was studied by isothermal compression test at temperatures range of 320 to 480 °C and strain rates range of 0.001 to 0.1 s −1. The true stresstrue strain curves were analyzed to characterize the flow stress of Al6061. Plastic behavior, as a function of both temperature and strain rate for Al6061, was also modeled using a hyperboli...

A method for measuring the real-time corrosion rates for Alloy 718, stainless steels (SS) 304L and 316L nuclear grade (NG), aluminum alloys 5052 (Al5052) and 6061 (Al6061), copper (Cu), tantalum (Ta), and tungsten (W) in two separate water systems that were irradiated by 800 MeV protons is presented. The ®rst water system was fabricated entirely of 304 SS, thoroughly cleaned before operation, a...

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% ...

In this study, to evaluate the effect of boron carbide (B4C) addition on wear performance aluminum (Al), Al6061 and 5, 10, 20 vol.% B4C/Al6061 composites were manufactured using stir casting hot rolling processes. B4C particles randomly dispersed during process; then, arranged in direction a process further improve dispersion resistance composites. Furthermore, continuous interfacial layer betw...

CoHErrelation between weldability and improvement in properties is a key issue in materials science research. The objective of this work is to optimize the process parameters viz., aging temperature, aging time, solutionizing time, to enhance the hardness of Al6061 alloy. Hence, the present paper deals with hardness study of Tungsten Inert Gas welded 6061 aluminium alloy after age hardening und...
