Preparation and Microstructure Characteristics of Aluminium 6061 Alloy Based Metal Matrix Composite

The role of engineering substances within the improvement of cutting-edge era like metallic Matrix Composites (MMCs) have evoked a eager hobby nowadays for capacity programs in aerospace and car industries as a result of their advanced power. Aluminium (6061) and Boron Carbide (Powder) is chosen for reinforcement material and matrix respectively. Al–B4C composites containing special weight probabilities 3.5 %, 7.0% and 10.5% of B4C have been fabricated by way of stir casting Technique. Experiments are conducted with the aid of various weight fraction of B4C (3.5%, 7.0% and 10.5%), at the same time as maintaining all other parameters regular. The compositions of their small structural options are determined through scientific discipline magnifier..

Issues in Potential IMC Application for Aerospace Structures

Intermetallic-matrix composites (IMCs) are intended for applications involving higher temperatures and stresses than conventional metallic matrix composites. Consequently, environmental effects, thermo-mechanical fatigue, interfacial thermodynamic stability, creep resistance, processing and cost are only a few of the obstacles to introduction in real products. The primary goal of current IMC development efforts is to provide ‘revolutionary’ materials for components that are enabling technologies in advanced demonstrator gas turbine engines. As compared to production applications, the hurdles for entry into demonstrator engine programs are not as high due to the limited operating time and the small number of parts to be produced. This paper examines the barriers to the introduction of IMCs in the context of application to production aerospace structures.
