Quality Features

Abstract In this paper it is stated, that a set of quality features of metal matrix composite castings differs from the same set for castings of classic materials, although some features are common for both of these material groups. These features (pertaining to a set of quality characteristics of composite castings) have been named as specific, they have not been determined yet and a description of material quality should be performed (according to the qualitology) on a principle of description of quality characteristics of this product. Therefore, this set of features has been determined. It was proposed to add the following characteristics to the set of specific features of composite castings quality: matrix material, reinforcement material, binding between components and porosity of the composite casting. In this set a sub-set of quality characteristics of composite castings was also determined.

Machining Rate

This study explores and demonstrates the effectiveness of employing Electro Discharge Machining (EDM) for processing ceramics particularly Metal Matrix Composite (MMC) materials. Conductive ceramics can be easily machined and non conductive ceramics can be made machinable by doping them with conductive metal particulates. In a related experimental study the effects of the concentration and size of these particulates are analyzed on the machining rate of MMC components.

Micro Indentation

The recently developed indentation techniques are awfully advantageous as they are performing in determination of hardness and local elasticity modulus for particular conditions; also they are being able to deal with small sample sizes. This technique is well used to characterize mechanical properties as hardness, elasticity and creep for coating thin layers. Experimental comparison of common nano and micro scales for hardness evaluation has been performed on metal samples and discussed in details in the literature review [1-3]. In fact, it was well detailed that instrumented indentation was found advantageous in both repeatability and a number of measured parameters over classical hardness methods for different materials. As far as thin materials are being very used in various industrial fields, the mechanical characterization moves to micro level scale, with micro-indentation tests of thin films and from Newton -to- micro Newton for loading conditions. A big step forward has been reached for load-depth monitoring during loading and unloading in indentation cycle. Nowadays, hardness and Young’s modulus can be easily defined using Oliver-Pharr [4-5] equations based on a micro scratch test of a very thin film. In this paper an experimental study is conducted and has been validated with a numerical FE model based on a micro indentation test of a metal matrix composite material 110A, used in aeronautic applications.
