In the current investigation, efforts are being made to produce an Al2014-Al2O3p composite with variable particle size of 88 mm by liquid stir casting route. 9, 12 and 15 weight proportions Al2O3p were added Al2014 base alloy. By using SEM EDS testing, microstructural studies have been conducted. Al2014-9, proportion composites mechanical behavior is determined in line ASTM standards. Electron ...

The nano-sized particle-reinforced metal matrix composites are the new potential material which could be applied in many industry fields, possess superior strength, ductility, and wear resistance comparison with micro-sized composites. However, fabrication methods of nanoparticles complex expensive. In present research, micron size SiC particles milled for 45-hours wet milling arrangement a pla...

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...

The microstructure and mechanical properties of an MMC based on AA 7075 strengthened through silicon carbide (SiC) as well boron (B4C) elements were studied. (SiC + B4C) combination was used in various weight percentages 4, 8, 12, 16% to create the hybrid composites utilizing traditional stir casting procedure. XRD SEM measurements investigate dispersion reinforced particles. For example, micro...

Metal matrix composites (MMCs) play a crucial role in the aerospace, automotive and mineral processing industries. The properties of aluminum (AMC) that are renowned for their high strength, good stiffness excellent thermal conductivity can be enhanced by incorporating various reinforcements. In this investigation, Al7075 alloy with TiC (3, 6, 9 wt.%) reinforcements was processed via stir casti...

Friction stir welding and tungsten inert gas welding techniques were employed to weld armor grade aluminum alloy to investigate the effect of welding processes on tensile behavior of weld joints. Tensile tests, Vicker microhardness tests and optical microscopy were performed on developed weld joints and base metal. Welding process influenced tensile behavior and microstructure of weld joints. F...

PURPOSE To compare the detectability of vertebral metastatic disease on T1-weighted, short-inversion-time inversion recovery (STIR), fast spin-echo (FSE), fat-saturated FSE, and inversion recovery FSE (IRFSE) MR sequences using percent contrast and contrast-to-noise ratios. METHODS Patients with proved metastatic disease underwent imaging on a 1.5-T MR system with sagittal T1-weighted (800/20...
