Abstract

Conditions of intermetallic phase synthesis during layerwise selective laser sintering/melting in Cu-Al-Ni powdered system were explored. There to we used optical and scanning electron microscopy, EDX and XRD analysis for microstructure testing and intermetallide identification in porous 3D samples depending on the laser syntheses regimes. A high laser sintering ability of the prepared mixtures and shape memory effect in 3D samples by results of specific electrical resistance measurements were shown. Porosity of the laser-synthesized Al7Cu4Ni intermetallide led to a peak shifting by the temperature axis and the intervals of the As-Af austenite transformation and Ms-Mf martensite transformation were 50 ÷ 80 °C and +25 ÷ -40 °C respectively.
