The Bureau of Mines conducted seven pioneering experiments in a 12- inch-diameter kroll reduction reactor to examine the feasibility of coreducing the chlorides of ti, al, and V to produce a homogeneous titanium alloy sponge. The coreduction studies proceeded in a normal manner, and the yields of sponge were comparable with those of pure titanium sponge made in the same reactor. Vanadium concentration was very uniform throughout the sponge cake when vcl4 in solution in ticl4 was fed into the molten magnesium. More difficulty was encountered in feeding solid vcl2 and alcl3. Vanadium and aluminum concentration in the sponge was not uniform, and mechanical difficulties were experienced with the small-scale screw feeder. Although the sponge varied in composition from region to region, the ingots prepared from it were uniform in composition.
