Abstract
Single crystals of β-CuZn have been deformed in direct shear in a wide range of temperatures in different shear systems. The shear systems studied were ⟨111⟩-{112}, ⟨111⟩-{110},⟨100⟩-{100}, ⟨100⟩-{110}, ⟨110⟩-{100} and ⟨110⟩-{110} systems. In the case of the ⟨111⟩-{112} shear system the crystals were deformed in both the twinning and the antitwinning senses. No significant difference was observed in the peak temperature T p when the crystals were deformed in the twinning and in the antitwinning senses. Based on the results obtained by the direct shear tests, the orientation dependence of the strength anomaly in β-CuZn, as studied by the conventional uniaxial deformation tests, has been discussed.Keywords
