$5.$ A rolled Cu$-30$ wt$\%$ Zn plate $0\mathrm{.}500-$in$.-$thick has a $2\%$ elongation as$-$received by thesupplier. The desired specifications for the final sheet are a thickness of $0\mathrm{.}125$ in$.,$minimum tensile strength of $70,000$ psi, and minimum elongation of $7\%.$ Assume that the rolling is conducted so that the width of the sheet is unchanged. Specify all steps in the procedure, including heat treatments.
