Capacitor Discharge Welding (CDM) is a rapid solidification joining process capable of cooling rates greater than 101 K/s. The Bureau of Mines is investigating the CDW process as a method of joining TiAl, Fe{sub 3}Al and MoSi{sub 2}. Experimental results show that the fusion zone of the CDW welds is less than 0.1 mm wide, is uniform in composition, and has a cellular solidification microstructure. This paper compares the CDW microstructure of several intermetallics to the microstructures obtained from the gas tungsten arc welding.
