Repeat Prob. 2–9 for a part made from hot-rolled AISI 1212 steel.
Repeat Prob. 2–9, A part made from annealed AISI 1018 steel undergoes a 20 percent cold-work operation.
(a) Obtain the yield strength and ultimate strength before and after the cold-work operation. Determine the percent increase in each strength.
(b) Determine the ratios of ultimate strength to yield strength before and after the cold-work operation. What does the result indicate about the change of ductility of the part?
