Patent CA-2532567-A1 (CA)
Inventor: JHA BIJENDRA
IPC: B01D53/34
Filed: 2004-08-09
Abstract: A FeCrAl alloy for catalytic converter substrates having excellent oxidation resistance and dimension stability at a medium high temperature, e.g. the temperature encountered by catalytic converter substrates in truck diesel engines, without necessary addition of extra Y, Hf, or rare earth elements beyond that inherently present in commercial stainless steel. A roll bonding and diffusion alloying annealing method is used for making such materials with the following two deviated paths. First, material in which layers of ferritic stainless steel and aluminum are solid state metallurgically bonded together forming a multilayer composite material. Such composite material is then further rolled to an intermediate foil gauge and then subjected to a thermal reaction to form a resulting uniform solid solution foil material followed by rolling to the final foil thickness. Alternatively, such composite material is further rolled to the final foil thickness and then subjected to a thermal in-situ reaction in the material after a honeycomb-like catalytic converter is made from the foil composite material. Both deviated approaches result in a uniform solid solution foil material.
