Abstract. The structural features of the sintered TiNi-based porous materials with terraced morphology of the pore wall surface have been studied. A porous alloy with the TiNi intermetallic compound in a two-phase state was produced by diffusion liquid-phase sintering of TiNi powder. In the samples obtained, the regions of melt formation exhibit a terraced relief of the pore wall surface. The terraces are located in the regions free of secondary-phase particles and propagate along the curved surface of the pore walls within one grain. Hexagonal areas are observed in some regions of the pore wall surface. The terraced relief is formed in the regions where the martensite crystals B19′ emerge on the surface of the pore walls.
