| 中文摘要 | The amorphous Sm2Fe15Ga2C2 ribbons were rapidly thermal annealed at various temperatures for various times. From the X-ray diffraction patterns, two phases, i.e. 2 : 17 phase and alpha-Fe, were always found when the ribbons were annealed at temperature above 700 degrees C. The demagnetization curves also verified this two-phase behavior. However, from the TEM studies, only 2: 17 phase was found. This led to the suggestion that the alpha-Fe precipitates were caused by the oxidation of Sm and only took place at the surface of the annealed ribbons. Moreover, from the TEM images, crystallization of 2 : 17 phase was found to begin at about 600 degrees C. The ribbons annealed at 700 or 900 degrees C for 1 min showed well-defined grains in the absence of alpha-Fe. Their grain sizes were measured to be about 100 nm for 700 degrees C x 1 min and 250 nm for 900 degrees C x 1 min, respectively. It was thus suggested that the Sm2Fe15Ga2C2 2 : 17 type structure obtained from the melt-spinning technique remains stable up to at least 900 degrees C. (C) 1999 Published by Elsevier Science B.V.
