Abstract

The deformation behaviour of solid aluminium alloy (LM6) and silicon carbide metal matrix composite cylinders under axi-symmetric compression over constant aspect ratios using different lubricants were examined. Dry condition and three different lubricants namely MoS2, graphite and white grease were prepared and cold upset forged. In the light of the previous studies, the calculations were made with the assumption that the curvatures of deformed specimens were in the form of a circular arc. The calculated radius of curvature of the bulge was found under different lubricating conditions. The flow curve of composite was determined by compression tests and data were used in simulation analysis. The FEA simulation was carried out using DEFORM software. Results gained by Finite Element Analysis and by experiment show high degree of similarity, so this way of modeling could be used for even more complex technology of plasticity.
