【摘要】 本文建立了一种用X射线衍射原理测定铁基非晶材料结晶度的方法。应指出这里的结晶度系指在固定保温时间和不同退火温度条件下的非平衡态晶化过程的结晶度。通过结晶度的研究,可提供控制晶化转变的依据。通过对通常的计算法则进行修正和简化,可得到结晶度与温度之间的关系,这与从实践中得到的客观规律十分符合,对于铁基非晶合金而言,这种结晶度的测试方法是适合的。更多还原

【Abstract】 In order to study iron-base amorphous alloys, a method of determining the crystallinity of amorphous alloys was established on the basis of x-ray diffraction principle in this paper. It should be pointed out that the crystallinity was the one of unstable equilibrium state in the process of crystallization of iron-base amorphous material under the conditions of varied temperatures and a given time of annealing. The study of crystallinities could provide the basis of controlling crystalline transformation. The investigation results showed that the relationship between the crystallinity and the temperature could be established by correcting and simplifying for the general theorem of calculation, which was in fair agreement with objective law obtained from the practice, and the method for the determination of crystallinity was suitable for iron-base amorphous alloys.更多还原
