非晶转变为纳米晶的一种新途径——非晶合金Fe_(78)B_(13)Si_9在激波作用下的晶化

A New Nano-Technology ——The Crystallization of Amorphous Alloy Fe 78 B 13 Si 9 under Shock Wave

用ＸＲＤ和ＤＳＣ研究了激波对非晶合金ＦｅＢＳｉ的影响，结果表明，一定强度的激波能使非晶态转变为晶态，且晶粒尺寸在纳米范围内。讨论了晶化机理。

The effects of shock wave on amorphous alloy FeBSi have been studied by differential scanning calorimeter (DSC) and X-ray diffraction (XRD). It has been found that the shock wave with certain intensity can make amorphous alloy change into a polycrystalline material and the grain size is within the range of nanometer. The mechanism of its crystallization was discussed.
