摘要

在本研究中，Zr44Ti11Cu10Ni10Be25 (at。研究了不同变形温度下的大块金属玻璃（bmg）吹塑过程。随着变形温度的升高，BMG的成形性增强，应变不均匀性明显。较高的变形温度促进了BMG的结晶。变形试样的不同区域结晶程度不同，顶部区域结晶率最高，这可归因于应变诱导结晶。热软化和结晶诱发的应变硬化共同作用使试样呈椭圆形。研究结果可为bmg吹塑工艺的优化提供理论指导，从而促进bmg的工业应用。

The deformation behaviors and structural evolution of a ZrCuNiAl bulk metallic glass during the blow molding

In this study, the deformation behaviors and structural evolution of Zr₄₄Ti₁₁Cu₁₀Ni₁₀Be₂₅ (at. %) bulk metallic glasses (BMGs) at different deformation temperatures were investigated during blow molding. As the deformation temperature increased, the studied BMG exhibited enhanced formability, accompanied by pronounced strain non-uniformity. Higher deformation temperatures promoted crystallization of the studied BMG. The degree of crystallization varied in different regions of the deformed sample, with the top region showing the highest crystallization fraction, which can be attributed to strain-induced crystallization. The combined effects of thermal softening and crystallization-induced strain-hardening contributed to the elliptical shaping of the studied sample. These findings may offer theoretical guidance for optimizing the blow molding process of BMGs and thus promoting their industrial applications.

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
