摘要：

Deformation behavior of binary stoichiometric Ti(5)Si(3) single crystals was examined as a function of the loading axis orientation and temperature. Two different types of deformation modes, namely {1100}[0001] prism slip, {2112}1/3 < 2113 > pyramidal slip were newly identified to be activated above 1300 C depending on the loading axis orientation. Critical resolved shear stresses (CRSS) for the {1100} [0001] prism slip and {2112}1/3 < 2113 > pyramidal slip were estimated to be about 130 MPa and 330 MPa at 1400 degrees C, respectively. The values of the CRSS for these two slip systems decrease monotonously with increasing the temperature.
