Microstructural characterization of a silicon carbide whisker reinforced 2014 aluminum metal matrix composite

Fabrication of Aluminum Matrix Composite Reinforced by Silicon Carbide of Various Micro-structures

Micro structural aspects of Aluminium Silicon Carbide Metal Matrix Composite

The role of engineering materials in the development of modern technology need not be emphasized. As the levels of technology have become more and more sophisticated, the materials used also have to be correspondingly made more efficient and effective. The increasing use of Aluminium alloy materials in structural and space applications generated considerable interest for the development of tech...

Microstructure and Fracture Toughness of Hot-Pressed Silicon Carbide Reinforced with Silicon Carbide Whisker

The effects of p-Sic whisker addition on the microstructural evolution and fracture toughness (K,c) of hot-pressed SIC were investigated. Most of the whiskers added disappeared during the densification process by transformation into the a-phase. The remaining whiskers acted as nuclei for grain growth, resulting in the formation of large tabular grains around the whiskers. The tabular grains aro...

Study on Iraqi bauxite ceramic reinforced Aluminum metal matrix composite synthesized by stir casting

For the past decades researchers are showing immense interest to investigate the natural advantage of preparation of composites from minerals such as bauxite particles, and proved their effectiveness as cost effective reinforcing agents in fabrication of high performance composites. This study, is a new attempt in using the Iraqi natural bauxite powder with different proportions (2wt%, 4wt%, an...

Microstructure and Mechanical properties of Multipass Friction Stir Processed Aluminum Silicon Carbide Metal Matrix

Abstrct :In this study, SiC particles were incorporated by using Friction Stir Processing (FSP) into the 6351 aluminium alloy to form particulate composite materials. Sampels were subjected to constant rotational and traverse speeds of the FSP tool with and without SiC reinforcements. Microstructural observations were carried out by employing optical microscopy of the modifiedsurfaces. Mechanic...
