Notes:
Pure Al (99%) and pure Fe (99.5%) sheets were mutually stacked and severely deformed upto equivalent strain of 16 by the accumulative roll bonding (ARB) process in an attempt to achievebulk mechanical alloying. The deformation was carried out at RT. The Al/Fe sheets ARB processedby 1 cycle showed a number of shear bands penetrating the stacked layers. The Fe layers, which wereharder than the Al layers, were subdivided by the shear bands into diamond-shaped regions.Dissolution of Fe into Al was observed and a supersaturated solid solution was formed in thespecimen ARB processed by 10 cycles. It was also found that local amorphization occurred atinterface regions via formation of Al5Fe2 intermetallic compound
