Martensitic Transformation And Structural Inhomogeneity In Fe72pt28 Induced By Mechanical Milling
JOURNAL OF MAGNETISM AND MAGNETIC MATERIALS(1998)
摘要
The effect of mechanical milling on the structure and magnetic properties of ordered Fe72Pt28 has been studied. The X-ray diffraction results suggest the presence of two kinds of transformation under milling; order-disorder transformation and the martensitic one. Moreover, the mechanically milled Fe72Pt28 was transformed into a FCC structure by heating up to 750 K. Structural inhomogeneity in heated samples, that were FCC Fe72Pt28, is found to depend on milling time. Magnetic behavior is suggested to depend on, primarily, the structures and the structural inhomogeneity induced by milling. (C) 1998 Elsevier Science B.V. All rights reserved.
