The paper deals with the deformation curves and fatigue tests of the porous nickel–titanium (NiTi) alloy produced with self-propagating high-temperature synthesis. Deformation curves obtained for tension and three-point bending of porous NiTi plates demonstrate their viscoelastic deformation due to the austenite-to-martensite phase transformation. Scanning electron microscopy observations of the fractured surface show the regions of quasi-brittle fracture of martensite and ductile fracture of austenite. Brittle fracture is observed for nonmetallic inclusions and the porous structure coating of the intermetallic compound. Fatigue tests show that the brittle phases and inclusions have no critical negative effect on the strain and fatigue properties of the NiTi alloy. It is determined that 70% of the porous alloy specimens withstand 106 cyclic bending owing to the reversible austenite-martensite phase transformation in the parent phase which is one the components of the multi-phase porous alloy.
