摘　　要：通过计算机模拟双相纳米晶合金(Fe0.5Co0.5)73.5Nb2V1Si13.5B9Cu1的X射线衍射峰,得出了合金经不同温度纳米晶化后的晶化体积,在520℃退火后合金晶化已基本完成,晶化体积达85%以上。对于(Fe0.5Co0.5)73.5Nb2V1Si13.5B9Cu1合金经不同温度退火后生成的纳米晶合金及其他合金退火后生成的纳米晶合金其晶化体积将会随退火温度的增加而增加,从而使其在高温下的软磁性能越趋于稳定。利用该方法得出的结果对纳米晶合金的这一特性解释得很好。这对研究双相纳米晶软磁合金的性能和结构特别是高温纳米晶的高温性能具有一定的意义。The crystalline volume fraction of two- based nanocrystalline magnetic alloys （Fe0.5Co0.5）73.5 Nb2V1Si13.5B9Cu1 has been achieved by stimulus X-ray diffraction patterns. It shown that as the annealing temperature came to 520℃, the alloys nanocrystalled completely, and the crystalline volume fraction got to 85 %. It is well known that the higher of annealing temperature, the more crystalline volume fraction would get in nanocrystalline alloys, then the performance of the alloys at high temperature would be well. The result can interprete the magnetic properties of （Fe0.5Co0.5）73.5Nb2V1Si13.5BgCu1 alloys at high temperature. Which also would be helpful to studied the properties and microstructure of nanocrystalline magnetic alloys.
