Open cell aluminum foams have good acoustic dampening properties. In this research, in order to improve the sound damping capacity of these foams, 0.9, 1.5 and 3wt% carbon nanotubes were added to the aluminum foam. Foams were produced by the space holder method in powder metallurgy. The results showed that Al-0.9wt%CNT nanocomposite foam had the highest average sound transmission loss in the fr...
This research is focused on the influence of processing temperature on titanium matrix composites reinforced through Ti, Al, and B₄C reactions. In order to investigate the effect of Ti-Al based intermetallic compounds on the properties of the composites, aluminum powder was incorporated into the starting materials. In this way, in situ TixAly were expected to form as well as TiB and TiC. The sp...
The physical and mechanical properties of samples of a nickel-base alloy fabricated by powder metallurgy were determined. The particle sizes of the powders used to make the samples varied from -80/ +200 mesh to -325 mesh. The compaction pressure varied from 138 to 414 MN/m2 and the sintering temperature varied from 1150 to 1250 degrees C. The shrinkage during processing, the porosity, tensile s...
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...
