Microstructural and mechanical characterization of aluminum-graphite composites Conference Paper uri icon

abstract

  • Aluminum-graphite Al-C novel micro-composites have been produced using the Mechanical Alloying process (MA). The mechanical properties of the obtained composites have been evaluated. Yield Strength (σy) values reached in the composites are considerably higher than that reported for pure aluminum. There is a direct relationship between σy and final metal-coated graphite content in the composite. σy values increase as the nominal C content increases as well. We found that the most important hardening element was the graphite.
