dissimilar aluminum alloys to fabricate a carbon/aluminum metal matrix composite (MMC)
joint. Carbon materials in the form of graphite powder are deposited on an aluminum sheet
at room temperature. Lap joints of dissimilar aluminum alloys are fabricated via FSSW using
the carbon-deposited aluminum sheet as the upper sheet of the joint. The Raman
spectroscopy confirms that carbon/aluminum MMC is successfully fabricated in the joint. The …
