摘要 用CO2 连续激光在不同功率、相同的速度条件下辐照Fe73 5Cu1Nb3 Si13 5B9非晶带 ,然后用穆斯堡尔谱详细研究材料的微观结构 .研究发现当扫描速度和散光斑直径一定的情况下 ,适当选择激光功率 ,Fe73 5Cu1Nb3 Si13 Soft magnetic amorphous Fe 73.5Cu 1Nb 3Si 13.5B 9 ribbons were exposed isochronally to CO 2-laser beam irradiation with the same velocity and defocused diameter but different laser powers. Then the micro-structure of the irradiated specimens were studied by M*issbauer spectroscopy.It can be concluded that micro- crystallization can be obtained when the power parameter is properly chosen.
