Abstract: Al-Cu particulate composites (5-15 wt%) are prepared by stir cast method by dispersing copper powders (filings) in molten aluminium. Al-5Cu alloy is also fabricated under similar processing conditions with mutual solubility. Composites show well engulfed reinforcement (copper particles) in Al matrix where as alloy reveals a well defined fine dendritic structure. Deformation (cold upsetting) studies are carried out and behavior is recorded using PC based logging system. Failure of the billet before 50% deformation has been observed for higher concentration of reinforcement composites. Comparative studies are made with the alloy having similar composition.
