| 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. |
