Mechanical properties and grinding performance on aluminum-based metal matrix composites

The metal matrix composites (MMCs) are attractive materials in the various areas of the industrial application because of their superior properties. This study presented the fabrication by the pressureless infiltration process under the nitrogen gas atmosphere, and the grinding of the aluminum-based MMCs reinforced with SiC particles. The working conditions such as the contents of the SiC and the Mg were examined how to influence the fabricating process of the MMCs. The effect of the grinding parameters on the surface roughness and the grinding forces was evaluated, and then the grinding parameters were optimized using the SIN ratio. The second-order response surface models were developed and the usefulness of the developed models was verified. (C) 2007 Elsevier B.V. All rights reserved.
