| 中文摘要 | Isotropic Gd(Co0.88-xCuxFe0.09Zr0.03)(7) (x= 0.10 - 0.20) ribbons with TbCu7 structure have been prepared by melt-spinning technique. A uniform and fine cellular microstructure consisting of 2: 17 cell with 1: 5 cell-boundary phase is developed by simply slow cooling the ribbons from 850 to 400 degreesC without the standard solid solution and isothermal aging treatments. It is interesting to note that the original grain boundary of 1: 7 phase still exists in the precipitation-hardened ribbons and the crystallographic texture is formed in each 1: 7 granular region after the treatment. This gives a way to fabricate the textured magnets with nanostructure. Positive temperature coefficients of remanence and coercivity are observed in the ribbons. The coercivity mechanism of the precipitation-hardened ribbons is discussed at the temperature ranging from room temperature to 600 degreesC. It is proposed that the residual 1: 7 phase boundaries act as effective pinning sites at high temperatures. (C) 2005 American Institute of Physics. |
