【摘要】：非晶態(tài)材料有著復雜的原子結構(短程有序、長程無序)和特殊的物理性質(zhì),其臨界現(xiàn)象和相變問題一直受到學術界關注.非晶合金,又稱為金屬玻璃,是一種新型的非晶態(tài)材料,具有很高的強度和優(yōu)異的彈性.從微觀的角度來看,非晶合金可以看作是一個多粒子系統(tǒng).臨界現(xiàn)象的研究對認識和理解多粒子系統(tǒng)之間的相互作用有深刻的意義.本文主要討論非晶合金中的臨界現(xiàn)象,包括非晶合金從制備過程、微觀結構到宏觀的力學性能以及磁性方面存在的臨界現(xiàn)象,并分析這些臨界現(xiàn)象之間的內(nèi)在聯(lián)系,進而深入理解非晶合金的微觀結構對其宏觀性質(zhì)的影響.這為認識非晶合金的形成本質(zhì),提高服役可靠性,探索具有實際應用價值的非晶合金提供理論依據(jù).
[Abstract]:Amorphous materials have complex atomic structures (short-range order, long-range disorder) and special physical properties, and their critical phenomena and phase transition problems have been concerned by the academic community. Amorphous alloy, also known as metallic glass, is a new type of amorphous material with high strength and excellent elasticity. From a microscopic point of view, amorphous alloys can be regarded as a multi-particle subsystem. The study of critical phenomena is of great significance to the understanding and understanding of the interaction between multi-particle subsystems. In this paper, the critical phenomena in amorphous alloys are discussed, including the critical phenomena in the preparation process, microstructure, macroscopic mechanical properties and magnetic properties of amorphous alloys, and the internal relations between these critical phenomena are analyzed, so as to deeply understand the influence of the microstructure of amorphous alloys on their macroscopic properties. This provides a theoretical basis for understanding the forming essence of amorphous alloys, improving the reliability of service and exploring the amorphous alloys with practical application value.
