| 摘 要： | 运用穆斯堡尔效应的方法考查了原始制备态和退火态的Fe_(73.1)Cu_(1.2)Nb_(3.2)Si_(12.5)B_(10)合金的显微组织。计算表明:退火的具有超细晶粒的微晶合金的显微组织主要由主晶相Fe_(75+y)Si_(25-y)型有序相和非晶态晶界相组成,可能含有很少量的顺磁相。组织中主相Fe_(75+y)Si_(25-y)含量大约为70％,非晶相约为26％。有序相Fe_(75+y)Si_(25-y)中的y在5—7之间。

| Abstract: | The microstructure of microcrystalline Fe73.1Cu1.2Nb3.2Si12.5B10 alloy has been examined by Mossbauer spectroscopy. The experimental results show that the microstructure of the alloy is composed of about 70% ordered phase Fe73+ySi25-y 26% amorphous phase as grain boundaries and a little paramagnetic phase. The y value in Fe75+ySi25-y has been preliminarily determined to be in the range of 5-7. |
