Aluminum Alloy Matrix

WAl12 reinforced 2024 aluminum alloy matrix composites were prepared by powder metallurgy with tungsten particles and W50Al50 alloy particles. The effects of WAl12 on the mechanical properties of 2024 aluminum alloy composites at room temperature and high temperature were studied, and the friction behavior was characterized. The results show that intermetallic WAl12 phase forms in the composite by 2024 aluminum alloy and tungsten. The mechanical properties and friction behavior can be improved by the formation of intermetallic WAl12 phase. The tensile strength of 2024 aluminum alloy at room temperature and 180 °C can be improved by adding tungsten less than 1.5 at.%. Adding 2.0 at.% tungsten can reduce the friction coefficient by 20 % and the scratch width by 40 %. The tensile fracture surface of the sample was analyzed by scanning electron microscopy (SEM), indicating that WAl12 intermetallic phase is closely connected with the aluminum matrix.

Powder metallurgy is one of the best methods to achieve uniform distribution of reinforcement in to the matrix. In this Paper, characterization of microstructure and hardness of aluminum alloy matrix composites reinforced with boron fiber particles prepared by powder metallurgy technique are investigated. The effects of boron fiber (Coarse particles size of 120 µm and Fine particles size of 50 µm) on mechanical properties were studied. Increasing the reinforcement of boron fiber content with 5%, 10% and15% into the matrix improved the mechanical properties. The percentage of boron fiber reinforcement increasing the strength of the hardness number is also increasing simultaneously, the aluminum alloys and boron fiber particles on the microstructure and mechanical properties of the composites were investigated. X-ray diffraction (XRD) and scanning electron microscopy (SEM) with Energy dispersive spectrum (EDS) analyses indicated. Analysis and observing microstructure of the composite is boron fiber particles are uniformly dispersed in the aluminum alloy matrix composites.

Incineration Ashes

This research article describes the newly developed composite material using the artificial pellets made of incineration ashes and recycled aluminum alloys. The factor affecting its various properties was investigated and discussed. Through trial and error, the hybrid preform with good soundness and preferable dispersion of the pellets could be obtained. The density and compression strength and thermal conductivity were measured in comparison of other structural materials.
