Question: We wish to produce a 0.3 in. thick plate of 3105 aluminum having a tensile strength of at least 25,000 psi and a % elongation

We wish to produce a 0.3 in. thick plate of 3105 aluminum having a tensile strength of at least 25,000 psi and a % elongation of at least 5%. The original thickness of the plate is 3 in. The maximum cold work in each step is 80%. Describe the cold working and annealing steps required to make this product. Compare this process with that you would recommend if you could do the initial deformation by hot working?
