Repeat the calculations in Example Problem 12.1, but use a lubricant with a coefficient of friction of 0.05 and a starting material with a size of 0.20 in. X 0.20 in. X 4 in. and flatten it to a thickness of 0.05 in. X 4 in. x M'.

Problem 12.1

a.       What are the stages of recrystallization?

b.      Estimate the recrystallization temperatures for pure copper, aluminum, lead, and iron and an AIST/SAE 1020 steel.
