Transformations and fine magnetic structure of mechanically alloyed Fe-Ni alloys

Structure and phase composition as well as fine magnetic structure of mecha nically alloyed (MA) Fe100-xNix compositions (x = 10, 20, 22, 24, 26, 28, 3 0, 32, 34, 36, 38, 40, 50, 60, 70, 80, 90 at%) were investigated by Mossbau er spectroscopy and X-ray diffractometry. The concentration ranges of exist ence of single-phase solid solutions for samples prepared by MA technique w ere extended comparing with the equilibrium alloys. Specialities of fine ma gnetic structure of as prepared and annealed MA samples were found to be in a good agreement with their phase composition. (C) 1999 Elsevier Science B .V. All rights reserved.
