1. Corrosion Investigation of Stir Cast Zn-27Al Based Hybrid Composites Reinforced with Quarry Dust and Silicon Carbide Particles
This paper investigates the corrosion behaviour of Zn-27Al based hybrid composites reinforced with quarry dust (QD) and silicon carbide particles (SiCp). The Zn-27Al hybrid composites containing 8 wt% and 10 wt% SiCp-QD particles reinforcement with varied weight percentage of 0, 25, 50, 75 and 100% quarry dust respectively were synthesized using stir casting

2. Effects of Processing Parameters on Microstructure and Mechanical Properties of Powder-Thixoforged SiC p /6061 Al Composite
A novel processing technology for the fabrication of particle reinforced metal matrix composites, powder thixoforming (PTF), was proposed and 6061 Al-based composites reinforced with 10% volume fractions of SiC particles (SiCp) were fabricated. The effects of processing parameters, such as reheating time, mould temperature and reheating temperature, on its m

3. Influence of graphite particles on surface roughness and chip formation studies in turning metal matrix composites
This study presents an experimental investigation on surface roughness and chip formation in turning of Al 2219/15SiCp and Al 2219/15SiCp-3Gr (hybrid) composites. Experiments were conducted with different cutting conditions using carbide, coated carbide and polycrystalline diamond (PCD) tools. The results reveal that the surface roughness values are less for

4. The use of fly-ash and rice-hull-ash in Al/SiCp composites: a comparative study of the corrosion and mechanical behavior
The corrosion characteristics and mechanical behavior of Al/SiCp/spinel composites prepared by reactive infiltration with fly-ash (FA) and rice-hull ash (RHA) -both with recycled aluminum- were investigated. MgAl2O4 is formed in situ during infiltration in the temperature range 1050-1150 °C for 50-70 min in argon atmosphere at a pressure slightly above to t

5. ObtenÃÃo e caracterizaÃÃo mecÃnica e microestrutural do compÃsito Al-5,0Si-1,0Cu/SiCp produzido por reofundiÃÃo
O compÃsito Al-5,0Si-1,0Cu/SiCP reforÃado com diferentes fraÃÃes volumÃtricas de partÃculas de carbeto de silÃcio (SiCP) foi elaborado e caracterizado microestruturalmente neste trabalho. A liga mÃe foi elaborada pelo processo de fundiÃÃo convencional num forno de induÃÃo de 24 KVA num cadinho de grafita. Depois de fundida e homogeneizada (T1050o
