Characterization Of Particulate-Reinforced Aluminium 6061 / Boron Carbide Composites
Aluminum-based metal matrix composite (MMC) materials are used in the design of ground transportation vehicles and aircraft. Compared with conventional, unreinforced alloys, composite materials usually exhibit higher strength, both at ambient and elevated temperatures, as well as good fatigue strength and wear resistance. MMCs could be produced by variety of methods such as Stir cast, Liquid In...
متن کاملComputational studies on high-stiffness, high-damping SiC–InSn particulate reinforced composites
With the objective of achieving composite material systems that feature high stiffness and high mechanical damping, consideration is given here to unit cell analysis of particulate composites with high volume fraction of inclusions. Effective elastic properties of the composite are computed with computational homogenization based on unit cell analysis. The correspondence principle together with...
متن کاملTENSILE AND FRACTURE CHARACTERISTICS OF A SIC- PARTICLE-REINFORCED 7075 ALUMINIUM ALLOY
Fracture behavior of a 7075 aluminium alloy reinforced with 15 Vol%. SiC particles was studied after T6 and annealing heat treatments under uniaxial tensile loading at room temperature. The scanning electron microscopy of fractured surfaces and EDS analysis showed:, that fracture mechanism changed from due mainly to fractured particle in T6 condition to interface decohesion in samples in anneal...
متن کاملCasting of SiC Reinforced Metal Matrix Composites
Composites based on two aluminium alloys (A536 and 6061) reinforced with 10% or 20% volume fraction of SiC particles were produced by gravity casting and a novel two-step mixing method was applied successfully to improve the wettability and distribution of the particles. The SiC particles were observed to be located predominantly in the interdendrit ic regions, and a thermal lag model is propos...
متن کاملGrinding of Aluminium-Based Metal Matrix Composites Reinforced with Al2O3 or SiC Particles
This paper presents results obtained from the grinding of aluminium-based metal matrix composites reinforced with either aluminium oxide (Al2O3) or silicon carbide (SiC) particles using grinding wheels made of SiC in a vitrified matrix or diamond in a resin-bonded matrix. The study used grinding speeds of 1100–2200 m min , a grinding depth of 15 m for rough grinding and 0.1–1 m for fine grindin...
