| 摘 要： | X射线衍射和透射电镜的结果表明：非晶FeCuNbMSiB（M＝Nb，V，Mo）合金在540 ℃退火20 min，表面析出的纳米晶是α-FeSi固溶体，粒度为10~20 nm。此外，在0.000 1~2.4 GPa范围内测量了它们的常压室温电阻率以及电阻率随静水压的变化，得到了电阻率与压力的线性关系式。最后探讨了热处理方式和温度对非晶Fe73.1Cu1.2Nb3.2Si12.5B10合金退火形成纳米晶的影响。

| Abstract: | The results on X-ray diffraction and transmission electron microscope indicated that crystallized nanophase was α-Fe(Si) solid solution in amorphous FeCuNbMSiB (M=Nb, V, Mo) alloys after annealing at 540 ℃ for 20 min. Graininess of α-Fe(Si) was 10～20 nm. Besides, their resistivity under atmospheric pressure and room temperature and variation of resistivity with hydrostatic pressure were measured in detail in the range from 0.000 1 to 2.40 GPa. Linear empirical equations of their relative resistivity to pressure were obtained by fitting on computer. Finally, effect of annealing mode and temperature on forming nanophase crystallization were discussed. |
