Powder Metallurgy (PM) Techniques consists in a suitable technique to process composites materials. A specific PM technique of mechanical alloying developed to produce new materials in the solid state is a consolidated route to obtain aluminum alloys metal matrix composites. Aluminum alloys metal matrix composites allies the good properties of aluminum and its alloys but with poor mechanical properties and the reinforcement of ceramics phases which add better mechanical properties to these alloys. The research of this materials processing by PM techniques presented new materials with improved properties. In this work an AA1100 aluminum alloy was reinforced by particulate silicon carbide and alumina types of ceramic phases. The powders were mixed and then processed by mechanical alloying in a SPEX vibratory type mill. Then the powders obtained were compacted and vacuum sintered. The sintered composites were characterized by means of Scanning Electron Microscopy (SEM) plus Energy Dispersive Spectroscopy (EDS) and Vickers hardness (HV) tests to evaluate the mechanical behavior.


Metal matrix composites (MMC) Are metals covered with diverse metals, stoneware or commonplace fragments. This essentially performed to beautify the homes of base metallic like high-quality, electricity, conductivity, and so on., Aluminum and its amalgams have pulled in most concept as a base steel in metallic lattice composites. Al MMC are typically applied in carrier, flying and severa area. This paper attempts to look the improvement of mechanical residences with the useful resource of the aggregate of Aluminum 6063 (Al6063) fortified with Silicon Carbide (SiC) and Mica composites made through combo tossing technique. The precedents are set up with aluminum changing with Silicon carbide via the use of weight percent of (12%, 13% and 14%) and mica (2%). Tests had been guided on these composites to evaluate how the flexibility, microhardness, flexural high-quality, compressive fine and microstructures of the materials were affected.
