Small punch creep tests under constant force were performed at the temperature of 623 K. It was shown that the fracture results, i.e. time to fracture and deflection at fracture were different in specimens with different orientation with respect to the axis of ECAP deformation. Fracture surface analysis of the tested small punch specimens was conducted. Fractures have transcrystalline ductile character. The fracture dimples are equiaxial as well as elongated in the dependence on strain direction. Fracture dimples are of two categories, the small ones sized from 0.1 to 0.5 mikron and large ones ranging from 3 to 6 mikron.
