非晶合金微观结构的不均匀性与塑性

块体非晶合金用于工程结构材料的优势在于其高强度和高弹性应变，瓶颈在于其缺乏塑性。近期的研究进展表明，在非晶合金中引入微观结构的不均匀性，可以获得良好的室温塑性。本文综述了块体非晶合金中各种微观结构不均匀性的形成条件、表征手段以及微观结构不均匀性与剪切带行为和塑性的关系，讨论了制备条件和合金成分对非晶合金微观结构和塑性的影响，并提出了非晶领域未来需要解决的几个重要问题

Correlation between Microscopically Structural Inhomogeneity and the Plasticity in Amorphous Alloy

The application of bulk amorphous alloys as structural materials is favored by their high strength and high elastic strain, but limited by their lack of plasticity. However, recent research advances show that the introduction of microscopically structural inhomogeneities results in excellent room-temperature plasticity of amorphous alloys. Various microstructural inhomogeneities in bulk amorphous alloys are reviewed in the present paper, with emphasis on their forming conditions, characterization techniques and correlations between shear banding behavior and plasticity. Influences of preparing conditions and chemical compositions on microstructure and plasticity of amorphous alloys are discussed. Finally, some unresolved fundamental issues in the amorphous field are highlighted
