The Mechanical properties and preferred orientation of beryllium-copper wire ware investigated as a function of cold work, annealing, and aging. Recrystallization and grain growth decrease the ratio of the torsional yield strength to the tensile strength. At the same time the proportion of the <111> component in the double <111>+<100> fiber texture increases. The change in mechanical properties with change in texture is in the direction one would predict from a consider consideration of the resolved shear stress imposed on the slip planes by torsional or tensile loading.
