In the present work the mechanical properties and especially fatigue behaviour of this type of nanoquazicrystalline material obtained in bulk form are described. For cyclic loading the cylindrical specimens were machined from two types of extrudates with different powder particle size (PPS). Fatigue properties were studied using servohydraulic MTS machine and cyclic loading was performed at constant stress amplitude with positive mean stress. Measured stress-strain data were evaluated and fatigue life in form of S-N curves was obtained. Fracture surface of broken testpieces was observed, fractographic analysis was performed and fracture mechanism was evaluated.
