The deformation behaviour of Ir3Nb with stoichiometric and off-stoichiometric compositions has been investigated as functions of crystal orientation and deformation temperature. The critical resolved shear stress (CRSS) for (111)[1¯01] slip in stoichiometric Ir3Nb exhibits a marginal temperature dep...
