Three different types of deformation modes – {View the MathML source}[0 0 0 1] prismatic slip, {View the MathML source}1/3left angle bracketView the MathML sourceright-pointing angle bracket pyramidal slip and {View the MathML source}left angle bracketView the MathML sourceright-pointing angle bracket twinning – were identified for the first time as being operative in Ti5Si3 at temperatures above 1300 °C, depending on the loading axis orientation. The critical resolved shear stresses (CRSSs) decrease steeply with increasing temperature for all deformation modes. The values of the CRSSs for {View the MathML source}[0 0 0 1] prismatic slip are considerably lower than those for {View the MathML source}1/3left angle bracketView the MathML sourceright-pointing angle bracket pyramidal slip, but are comparable to those for {View the MathML source}left angle bracketView the MathML sourceright-pointing angle bracket twinning. The favored deformation modes are discussed on the basis of anisotropic elasticity theory of dislocations.
