Deformation and fracture characteristics of Al6092/SiC/17.5p metal matrix composite sheets due to heat treatments

TEM micrographs of the interface of the 6092Al/SiC composites under different heating conditions. (a) TEM image of Al/SiC interface showing the intermetallic compound (Al2Cu) formed around the SiC particle after T6 condition and (b) TEM image of the Al/SiC interface showing the phase of Al4Cu2Mg8Si7 formed around the SiC particle after O-condition.139
