Casting experiments were conducted to determine the effects of alloying on the castibility of titanium. Commercially pure titanium and seven alloys were examined. All of the alloys were found to be castable; however, minor changes in fluidity and mold filling characteristics can be effected by alloy composition. Data indicate that both silicon and molybdenum tend to decrease the flowability of titanium, probably because they tend to drastically expand the freezing range. Manganese was demonstrated to have a degrading influence on castibility because of the rapid extraction of heat from the melt due to vaporization of manganese. This is probably true for all high-vapor-pressure elements. On the other hand, aluminum tends to raise the heat of fusion of titanium and as a consequence improves flowability.
