Roll Bonding and the Application in Making FeCrAl Alloy

Abstract:

Fe-21Cr-6Al-0.03(Ce+La) alloy has been made by an innovative method of roll bonding and diffusion alloying for catalytic converter metal foil substrate used for exhaust emission control. During the processes, roll bonding is applied to make a sandwiched Al/Fe22Cr/Al composite material from aluminum and Fe22Cr alloy. Conversion from the composite to the FeCrAl alloy can be accomplished by in-situ diffusion alloying during a thermal process of the converter fabrication.
