Аннотация

Topology of the surface micro- And nano- structures induced by the synthesis of NiTi intermetallic phases under Selective Laser Sintering is studied by Scanning Electron Microscopy. According previously developed us method, those data were analysed by image processing software for identification and discussion of common features and peculiarities of the phase and structural transformations. It was shown, that fine substructures have self- ordering nature. Geometric similarity of synthesizing structures expects their fractal nature. The dependence between the fractal dimension -D of low-dimensional nanostructures and laser energy input -A was found. The change of the fractal dimension of low dimensional structures clearly correlates with the change of roughness, while the increase of the laser energy input influences the fractal dimension - D in different ways. Shown that particularities of phase structural transformations at the intermetallic synthesis in the Ni-Ti system have been defined an appcarance of nano sized and self-ordering substructures of cellular, dendrite or mosaic types. A sharp variation of the D orientation indicates about of change of the phase- formation mechanism.
