Abstract: In the present study the aluminium reinforced with 10% SiCp particulate composites were produced through powder metallurgy route and processing map was developed. The composite specimens were subjected to compression test at different strains, strain rates and temperatures. Using the load-stroke data, flow stress-strain were evaluated. Fuzzy logic has been implemented for the prediction of flow stress. Power dissipation efficiency and instability parameter were evaluated and plotted with temperature and stain rate using the predicted values of flow stress from fuzzy logic. The contour plots were superimposed to obtain the processing maps. The dynamic recrystallisation zones and instable zones were identified and validated through micrographs. The processing maps can be used to select optimum strain rates and temperatures for effective hot working of Al/10% SiC composites. © 2006 Elsevier B.V. All rights reserved.
