The effect of chemical composition and the hot rolling operations on the microstructure and mechanical properties of in situ aluminum matrix composite with Mg2Si phase as the reinforcement was studied. It was revealed that the modification by phosphorous results in the rounder (more spherical) primary and secondary (eutectic) magnesium silicide intermetallics. During hot rolling, the primary pa...
Abstract This study used aluminum scraps to produce a secondary metal matrix for heat storage analyses. Silica and kaolin reinforced composites were successfully produced via stir casting. The X-ray diffraction (XRD) scanning electron microscopy (SEM) employed phase microstructure characterization. XRD revealed alumina (corundum), kyanite phases while SEM indicated pores in the composites. Dens...
A tensile test was carried out for continuous SiC fiber reinforced aluminum matrix composites (SiC/Al), which have different specimen width and length. A Monte Carlo simulation using finite element method was also performed with changing the width and length of composite model. The size effect of strength reliability was examined and discussed. The results showed that composite strength does no...
In this research, surface composite layers containing nano sized TiB2, Al2O3-TiB2, ZrO2 and CNT particles have been fabricated on Aluminum alloy substrates by friction stir processing. The effects of different processing variables such as number of passes and strengthening particle distribution, hardness, and wear properties of surface nano...
The aim of this study was to evaluate the shear bond strength of a composite resin to dental enamel, using three different surface treatments. Fifteen sound third molars were randomly assigned to three groups. The mesial and distal surfaces were flattened and covered using adhesive tape with a central orifice delimiting the adhesion area (7.07 mm2). Group I, the enamel surface was conditioned w...
in this work, a new aluminum matrix nanocomposite reinforced with beta-magnesium aluminide nanoparticles was produced by powder metallurgy technique. the prealloyed al-40 wt.% mg intermetallic ingot was milled for 100 hours to synthesize β-al3mg2 nanoparticles with the average size of 25 nm. different amounts of nanoparticles were added to al matrix powder and the mixture was then milled for 10...

An Al/Stainless Steel/Al lamellar composite was produced by roll bonding of the starting sheets at 400 °C. Afterward, the roll bonded sheet was cut in half and the accumulative roll bonding (ARB) process at room temperature was applied seven times. As a result, the central steel layer fractured and distributed in the Al matrix among different layers introduced by the repetition of roll bonding ...
in the present work, the aa2124/25vol.%mosi2 composite was produced by powder metallurgy technique. the aluminum alloy 2124 powder was produced by gas atomization method and the mosi2 intermetallic particles were produced through combustion synthesis. the aa2124 matrix powder was mechanically blended with 25vol.%mosi2 using a ball milling mixer. the blended powder mixture was encapsulated and t...
