Abstract:
Thermography and powder x-ray diffraction analysis were employed to examine high-temperature synthesis of nickel aluminide Ni$_3$Al based intermetallic composite materials by the thermal shock of a powder mixture of pure elements with an inert filler. The influence of the inert component on the phase composition of the final product of the synthesis reaction is studied. The final product is assumed to be formed owing to reaction diffusion at the stage of cooling of the thermoreactive powder system. Thermokinetic constants of formation of the NiAl and Ni$_3$Al phases are estimated. Regions of optimum regimes of high-temperature synthesis of the intermetallide Ni$_3$Al are determined.
Keywords:
high-temperature synthesis, intermetallide Ni$_3$Al, thermokinetic coefficients, cooling, crystallization, phase composition.
