摘要：

The gas release from nickel nanocrystalline powders fabricated by means of ultrasonic treatment in ball mill is investigated by mass spectroscopy, X-ray analysis, and magnetic measurements. As shown, the ultrasonic treatment of Ni coarse-grained powders results in considerable refinement of their microstructure: powders consist of conglomerates of particles sticking together with sizes less than 10 nm. The ultrasonically treated Ni powders contain impurities, whose atoms penetrate into Ni particles during ultrasonic treatment. The gas release process has complex character, and it is caused by leaving of oxygen, hydrogen, and carbon atoms from bulk and surface of nanoparticles. Magnetic properties of Ni powders change essentially after ultrasonic treatment. It is caused by the structure refinement of initial coarse-grain powders and by impurities penetrating into powders during ultrasonic treatment.
