Right answer is (a) True
The best I can explain: Titanium metal has a high melting point and low thermal conductivity which is responsible for producing a STEEP thermal gradient in the casting during solidification. The reaction with mould materials forms surface LAYERS which include oxygen and other elements taken from the mould. This affects the mechanical PROPERTIES of the castings. So to avoid such problems, graphite or INVESTMENTS moulds are used instead of simple moulds.
