4. Consider cooling curve below and 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. Is the solidification process homogeneous or non- homogeneous? (hint: if there is any undercooling, that will results in homogeneous solidification) Temperature (C) 500 400 300 200 12 cm 4 cm 100 0 0.8 cm 100 200 300 400 500 600 Time (s) 4.
