1. Two thick slabs of 300mm each, the first one is used in cold rolling where u=0.08 while the second is used in cold rolling where u-0.5. The mill roll diameter in each case is the same as 600mm. Determine the max draft (reduction) in both cases. Discuss the wide difference in results. 2. A tensile specimen of the metal of 100 mm is length stretched to a length

Questions:
1. Two thick slabs of 300mm each, the first one is used in cold rolling where
u=0.08 while the second is used in cold rolling where u-0.5. The mill roll
diameter in each case is the same as 600mm. Determine the max draft
(reduction) in both cases. Discuss the wide difference in results.
=
2. A tensile specimen of the metal of 100 mm is length stretched to a length
157 mm during the rolling process. If the metal has a flow curve with
parameters: K = 850 MPa and strain hardening exponent n = 0.30. Determine
the average flow stress that the metal has been subjected to during the
deformation.
