Morphological and Mechanical Characteristics of Hybrid Aluminium Matrix Composites
Main Article Content
Abstract
In emerging trend day by day the world facing lot of new invention in automobiles and aerospace industries. They need new smart materials lighter in weight, tensile strength and hardness with good thermal shock resistance compared to available conventional metals. Especially the aluminium based Metal Matrix Composite (MMC) materials can provide these properties. In this research article an attempt is made to find the mechanical properties and morphological of the aluminium alloys of Al 356 mixed with silicon carbide particles (SiCp) and Mica. All these three different MMCs were fabricated in stir casting method. Their tensile strengths are studied and compared with the help of Vickers micro hardness tester and tensile testing machine. The morphological characteristics are tested and compared with the Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDAX) optical microscopy. The tensile strength and hardness of MMCs were comparatively increased than the aluminium alloys.
