A simulation study on the transition feature of the microstructure in the forming processes of amorphous metals

摘要

It is well known that amorphous metals prepared by rapid cooling from liquid state have many excellent macroscopic properties, and this is mainly determined by their special microstructures. Accordingly, to understand the relationship between the structures and properties, it will have important theoretical and practical significance to find out the transition feature of the microstructural configurations by tracking the forming process of amorphous metals. However, under the present experimental conditions, it is very diffcult to perform such a tracking research. With the rapid development of computer technique, it is possible to make a simulation study, using the molecular dynamics method to get a very clear physical picture on the instantaneous processes of the microstructural configurations of liquid metals, and many important results have been obtained.
