“…matrix material (Al-5% Cu), size (average 3.5 μm) and volume fraction (15%) of reinforcement, are different as compared to those of Figure 1. Chen et al (2000) fabricated SiCp reinforced with A 356 alloy matrix by molten liquid aluminium stirring method, whereas Davidson and Regener (2000) manufactured 10 wt.% of SiCp-reinforced AA 6061 matrix composite by double-sided cold compaction process applying a pressure of 385 MPa for 5 min followed by pressureless sintering at 610°C for 5 h. Kumar and Dwarakadasa (2000) prepared 9% and 18% SiCp (of average particle size 40 μm) reinforced Al-Zn-Mg alloy (equivalent to Al 7075) matrix composites by liquid metal processing or stir casting technique. Figure 3 shows the size, shape and morphology of SiCp used.…”

“…Finally, they were aged at a temperature of 200°C for 5 h in air. Davidson and Regener (2000) solution-treated SiCp/AA 6061 composites at 530°C for 1 h and then quenched them in cold water, followed by ageing for 8 h at 175°C. Hamed et al (2001) subjected SiCp-reinforced Al 359 composite to T6 heat treatment which involved solution treatment for 16 h at 530°C, quenching at 60°C and then ageing for 9 h at 160°C.…”

Ceramic-reinforced aluminium matrix composites have attracted considerable attention in engineering applications as a result of their relatively low costs and characteristic isotropic properties. Reinforcement materials include carbides, nitrides and oxides. In an effort to achieve optimality in structure and properties of ceramic-reinforced metal matrix composites (MMCs), various fabrication and heat treatment techniques have evolved over the last 20 years. In this paper, the status of the research and development in fabrication and heat treatment techniques of ceramic-reinforced aluminium matrix composites is reviewed, with a major focus on material systems in terms of chemical compositions, weight or volume fraction, particle size of reinforcement, fabrication methods and heat treatment procedures. Various optical measurement techniques used by the researchers are highlighted. Also, limitations and needs of the technique in composite fabrication are presented in the literature. The full potential of various methods for fabricating ceramic-reinforced aluminium matrix composites is yet to be explored.

The present paper involves firstly in the studies of corrosion properties of Al 6061 metal matrix composites reinforced with varying percentage of uncoated and Cu coated silicon carbide in 3.5 wt% NaCl solution using weight loss method. The processing route used for the composites was stir casting technique. Mass loss and corrosion rate measurements were utilized as criteria for evaluating the corrosion behavior of composites. The surface morphology of composites after the corrosion test is determined by using scanning electron microscopy. It has been observed that copper as reinforcement coating reduces the corrosion resistance of composites in comparison to uncoated reinforcements and monolithic alloy.

“…Esto conduce a una estructura bien diferenciada con respecto a los composites con refuerzos en forma de partículas, fibras cerámicas reforzadas o cerámicas con inclusiones metálicas. Las técnicas más utilizadas para su fabricación son infiltración reactiva, infiltración por presión isostática en caliente (HIP) y sinterización [2] . En ellas, el metal debe tener una buena mojabilidad sobre el substrato y, en lo posible, una baja reactividad, con el objetivo de evitar que el substrato (cerámico) sea degradado por efecto de las reacciones químicas entre éste y el metal.…”

ResumenSe estudió la evolución microestructural de composites de SiC/aleaciones Cu-Si obtenidos a través del proceso de infiltración reactiva a 1400°C. Se detectaron tres zonas en los composites obtenidos: zona de reacción, transición e infiltrada. En la zona de reacción y de transición, la microestructura resultante estuvo compuesta por una fase metá-lica, láminas de grafito y partículas de SiC. Se encontró que el SiC se descompone en estas zonas por efecto de la aleación Cu-Si, por lo que el silicio disponible forma una solución líquida que a temperatura ambiente estuvo formada por una solución sólida α y una fase γ (Cu 5 Si). El carbono resultante de la descomposición del SiC precipitó como láminas de grafito. Además, la descomposición del SiC fue disminuyendo a medida que la cantidad de silicio en la aleación inicial se incrementó. Palabras claveInfiltración reactiva; Descomposición SiC; Composite SiC/Cu; Microestructura. Microstructural evolution of SiC/Cu-Si composites obtained through reactive infiltration AbstractThe microstructural evolution of composites of SiC/Cu-Si alloys obtained through process of reactive infiltration to 1400°C was studied. Three zones were detected in the obtained composites: the reaction zone, the transition zone and the infiltrated zone. In the reaction zone and transition zone the resulting microstructure was composed of a metallic phase, graphite laminae and SiC particles. It was found that SiC decomposes into these areas because of the alloy Cu-Si, so the available Si forms a liquid solution that a room temperature consisted of a α solid solution and a γ phase (Cu 5 Si). The carbon resulting from the decomposition of SiC precipitated as graphite laminae. In addition, the SiC decomposition was decreasing as the initial amount of Si in the alloy increased. KeywordsReactive infiltration; Decomposition SiC; Composite SiC/Cu; Microestructure. INTRODUCCIÓNLa alta resistencia al desgaste, el bajo peso específi-co, la alta rigidez y el bajo coeficiente de dilatación térmica hacen al SiC un material muy atractivo para aplicaciones en ingeniería [1] . Sin embargo, la nula tenacidad tanto al impacto como a la fractura y la baja resistencia al choque térmico se presentan como las dos principales desventajas de este material. Por el contrario, los metales de transición poseen altos valores de tenacidad y, en especial, los del grupo IB tienen excelente conductividad térmica y eléctrica.Desde la Segunda Guerra Mundial se han desarrollado los materiales compuestos. Dentro de este grupo de materiales están los composites cerámi-co-metal (CCM). Los CCM son redes interconectadas en el espacio de ambas fases. Esto conduce a una estructura bien diferenciada con respecto a los composites con refuerzos en forma de partículas, fibras cerámicas reforzadas o cerámicas con inclusiones metálicas. Las técnicas más utilizadas para su fabricación son infiltración reactiva, infiltración por presión isostática en caliente (HIP) y sinterización [2] . En ellas, el metal debe tener una buena mojabilidad sobre ...
