WebPure metals melts and solidify at a single temperature which may be termed as Melting point or Freezing point (FP). The following Figure shows the cooling curve (Time- Temperature curve) of pure metals:- 1- Liquid metal cools from A to B. 2- From B to C, the melt librates latent heat of fusion; temperature remains constant.
