Metal matrix composites (MMCs) have superior mechanical strength and wear resistance as compared to base alloy. Aluminium matrix reinforced with low density discontinuous particulate composites has good potential in automobile and aerospace applications. The main challenge is to produce the light weight composite in a cost effective way to achieve the greater properties. In the present study, a...

This paper begins a series studying D-modules on the Feigin-Frenkel semi-infinite flag variety from the perspective of the Beilinson-Drinfeld factorization (or chiral) theory. Here we calculate Whittaker-twisted cohomology groups of Zastava spaces, which are certain finite-dimensional subvarieties of the affine Grassmannian. We show that such cohomology groups realize the nilradical of a Borel ...

In this study, metal matrix-based composite (MMC) was subjected to Equal Chanel Angular Pressing (ECAP) in several passes determine the influence of deformation on hardness samples. Composite based A356 aluminum alloy and reinforced with Fly Ash (FA) particles obtained by compo casting method. The microstructural analyses microhardness measurements were performed cast pressed Vickers measuremen...

This paper presents an experimental design approach to the process parameter optimization for compocasting of A356-SiCp composites. Toward this end, parameters of stirring temperature, stirring time, stirring speed and SiC content were chosen and three levels of these parameters were considered. The D-optimal design of experiment (DODE) was employed for experimental design and analysis of resul...
