Abstract The analysis of die-cast 380 aluminum-boron carbide particulate metal matrix composites (MMC) was performed in order to see if the samples had the required tensile strength of 300 MPa. 10 wt% B 4C die-cast samples were produced and tested.Half
The addition of 20 w-% silicon carbide should have a dramatic effect on the Young’s modulus of cast aluminium alloys. Indeed, an increase from 75 GPa to 106 GPa is seen for the T6 condition (Table 1). Adding aluminium oxide made the situation worse. This
Silicon carbide fiber is a kind of high-performance ceramic material with carbon and silicon as the main components. Morphologically, it is divided into whisker and continuous silicon carbide fiber, and it has the advantages of high-temperature oxidation resistance, high hardness, high strength, high thermal stability, corrosion resistance, and low density.
Solid solubility of aluminum in silicon carbide was studied by the powder X‐ray diffraction technique (Debye‐Scherrer method). At 2200 C the solubility limit was 1.0 wt%. Measurements of the lattice parameter of Al‐saturated samples as a function of temperature

In this paper aluminium silicon carbide in the proven composition 25 % Silicon Carbide and 75 % Aluminium has casted by using stir casting process as per standard dimensions (ASTM E399). With the same dimension aluminium silicon carbide composite with added carbon nanotubes were also casted in the ratio 0.2 % multi walled Carbon Nanotube, 24.8 % Silicon Carbide and 75 % Aluminium.
Aluminum silicon carbide (AlSiC) metal matrix composite (MMC) packages have a unique set of material properties that are ideally suited to the above requirements. The AlSiC coefficient of thermal expansion (CTE) value is compatible with direct IC device attachment, allowing for the maximum thermal dissipation into the high thermal conductivity (170-200 W/mK) AlSiC package.
