Abstract

The yield stress properties and the associated slip systems of stoichiometric NiAl single crystals were investigated in terms of crystal orientation, temperature and the deformation mode. The CRSS was, in a wide range of experimental conditions, higher in the sequence of {110}<100>, {100}<100> and {hk0}<100> slips. In all the crystal orientations studied, the CRSS in compression was higher than the CRSS in tension particularly at low temperatures. The tension-compression asymmetry on the CRSS was understood qualitatively as being due to the effect of the normal stress on the core structure of a <001> dislocation.
