8) Other thermally more stable refractory oxide materials (calcium oxide, magnesium oxide and aluminum oxide) have been developed, but they have shown thermal expansion unable to compensate for the casting shrinkage of molten titanium.

Consequently, liquid metal was able to compensate casting shrinkage, which decreased the alloy's tendency to form shrinkage porosity and hot tears.
