13- Copper-rich copper-beryllium alloys are precipitation hardenable. After consulting the portion of the phase diagram shown in the figure below, do the following: (a) Specify the range of compositions over which these alloys may be precipitation hardened. (b) Briefly describe the heat-treatment procedures steps (in terms of temperatures) that would be used to precipitation harden an alloy having a composition of 1 wt% Be.
