Structure formation in titanium-carbide-steel alloys during sintering (part II)
- 38 Downloads
Two types of microstructure have been found in alloys sintered in a range of temperatures in which eutectics unsaturated and supersaturated with titanium carbide can exist: a microstructure consisting of fine polyhedral TiC grains with jagged edges and one consisting of large TiC grains of spheroidal shape.
Two types of titanium carbide ring structure are possible: One forms as a result of the coalescence of fine grains around austenitic steel grains and the other as a result of diffusional dissolution of the alloying elements of the steel in the titanium carbide.
