Below is a cooling curve:

Below is a cooling curve: Find: - pouring temperature, solidification temperature, superheat,

Find: - pouring temperature, solidification temperature, superheat, cooling rate just before solidification begins, total solidification time, local solidification time, and the probable identity of the metal.

If the cooling curve was obtained at the center of the casting sketched in the figure, determine the mold constant, assuming that n = 2.
