大块非晶合金形成能力的研究与进展

Research Status and Trends of Glass Forming Ability of Bulk Amorphous Alloys

如何准确地表征和预测合金的高非晶形成能力一直是非晶合金研究领域的热点和重点之一,各种表征和预测大块非晶合金形成能力(GFA)的参数和判据也被相继提出。本文回顾和分析了各种表征GFA的判据,尤其是近年来新提出的参数判据。并由此得出,合理的参数判据对于合金GFA的准确表征和大块非晶合金的发展尤为重要。

Glass forming ability (GFA) is very important for designing new bulk metallic glasses (BMGs).And different indicators of GFA for BMGs are proposed since 1960.These criteria,such as Rc,Kgl,Trg,ΔTx,γ and φ,are summarized here.In addition,limitations of some parameters are discussed.
