FOR THE TWO GRAPHS (#1 & #2) ANSWER THE FOLLOWING:

(explain how you found the answer for higher points/ratings)

a. What is the pouring temperature?

b. What is the freezing point (solidification temperature)

c. What is the superheat?

d. What is the total solidification time?

e. What is the local solidification time?

f. What is a likely identity of this metal? (Why)

g. Is this metal well inoculated?

h. How much was this metal undercooled? (degrees of undercooling)

Which casting process would you expect to return a stronger metal? Why?

a). pouring temperature is 1200 C as this was the temperature when t=0 see y intercept

b) freezing temp= 1000 c as at this temp cooling curve is horizontal for some time

c).super heat is 200 as 1200-1000=200

d).it is 45-10=35 min

e).it is 30 min

f).solid because at room temprature it will exist in solid form

g).no

h).100 degree
