A cooling curve is shown in Figure 9-27.

Determine

(a) The pouring temperature;

(b) The solidification temperature;

(c) The superheat;

(d) The cooling rate, just before solidification begins;

(e) The total solidification time;

(f) The local solidification time;

(g) The undercooling; and

(h) The probable identity of the metal.

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