Using the X-rays diffraction and magnetic properties measuring methods (vibrating sample and SQUIDmagnetometers) in this work the phase composition and magnetic hysteresis properties of rapidly quenched Nd9Fe74B12Ti4C alloys (ribbon flakes shape) prepared by the melt spinning centrifugal method with and without electric current passing through a melt jet, have been studied. The flakes were subjected to a short time annealing treatments in the temperature range between 550 – 1000°С. It was found, that rapidly quenched alloy (RQA) obtained with electric current passing has a “more deep” amorphous state (contains larger volume of amorphous phase) in comparison with the same RQA made without electric current passing. The anisotropy of hysteresis magnetic properties for RQA annealed at Т a = 720°С after their magnetizing along and in the perpendicular to the flake surface directions has been discovered. It was explained by the fan-type c-axis texture formation of Nd 2Fe 14B phase nuclei coursed by the melt spinning centrifugal method and succeeding short time temperature treatments giving their growing up to nano scale sizes.
