The reason is that liquid metal (having a higher concentration of alloying elements)

An increase in alloy content shifts the TTT curves to the right and Alloying elements also modify the shape of the TTT diagram and separate the ferrite + pearlite region from the bainite region making
Effects of Alloying Elements on Cobalt Silicide Formation
www.bnl.govWe demonstrate that alloying elements can sub-stantially affect the formation of cobalt silicide. A com-prehensive study of phase formation was performed on 23 cobalt alloys with alloying element concentra-tions ranging from 1 up to 20 at.%. Using in-situ char-acterization techniques in which x-ray diffraction and
