小角X射线散射技术确定Cu_(73)Sn_6Ni_6P_(15)非晶合金晶化相粒子特征函数v_0(r)

Determination of the Characteristic Function v_0(r)of the Particle of Crystallization Phase by Small Angle X-ray Scattering in Cu_(73)Sn_6Ni6P(15) Metallic Class

把非晶合金加热到一定的温度并保持一定时间,将会出现晶化。晶化相和非晶基底一般具有不同的电子密度,此密度差是产生小角x射线散射现象的起因,故而小角x射线散射技术(SAXS)是研究非晶合金结构弛豫和晶化初期生成的结晶相的形态特征的有效方法。 本文使用SAXS技术确定了Cu_(73)Sn_6Ni_6P_(15)非晶合金晶化相粒子特征函数v_0(γ),粒子的表面积与体积之比S/V_P值,粒子特征长度<L>和粒子回转半径R_G。

In this paper the characteristic function V_0(γ) of the particle, gyration radius R_G and characteristic length <L> of crystallization phase were determined by Small angle X-ray scazttering (SAXS) in Cu_(73)Sn_6Ni_6P_(15)metallic glass.
