由于非晶态合金的各种物理化学性能都与微观结构有关,而目前的实验手段尚不能完全确定其微观结构,为要深入研究结构与性能的关系,就必须借助于理想化模型,为此,本文在Bernal、Finney等人工作的基础上,对于由液态淬火制备的非晶态合金,提出可用双层单元结构模型来描述,并用此模型导出非晶态合金中类金属成分范围的上限约为30.47 at％,与已有实验结果甚为相符,又用此模型合理地解释了非晶态Fe-Si-B系合金中Tc极大值出现在类金属总成分约为25 at％左右等重要实验结果。
Because of the various physical and chemical properties of amorphous alloys are related to the microstructure, and the current experimental means are not yet fully determine the microstructure, in order to study the relationship between structure and performance, we must rely on the idealized model, for which Based on the work of Bernal and Finney et al., This paper presents a two-layer cell structure model for amorphous alloys prepared by liquid quenching. The upper bound of the metal-like composition in amorphous alloys Is 30.47 at%, which is in good agreement with the existing experimental results. It is also reasonably explained by this model that the maximum value of Tc in amorphous Fe-Si-B alloys appears at about 25 at% Important experimental results.
