It is shown by comparing the three compounds CuZn, FeAl and CoTi that factors governing the choice of the slip direction are more varied. They are, in particular the elastic anisotropy, types of planar faults on {110} planes with which dislocations can dissociate and the energy of these faults that is not simply related to the order-disorder transition temperature. It is explained why in FeAl the slip system is the same as in CuZn, i.e., 111{110}. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2011
