Abstract
A process is provided for producing aluminum-titanium-boron grain refining master alloys containing soluble titanium aluminide and insoluble aluminum boride particles, the process comprising mixing aluminum-boron alloy powder and K2TiF6 salt to obtain a blended mixture, heat treating the mixed powder blend thus obtained in an inert gas furnace just below the melting point of aluminum, at approximately 650 degrees Celcius sufficiently long and compacting the heated powder blend in the form of tablets. The cast grain size of an aluminum- 7 wt % silicon foundry alloy after inoculation with this master alloy at an addition level of 0.02% Ti was less than 200 microns for contact times of upto 15 minutes.
