摘要

原则上,金属玻璃的韧性到脆性转变(DBT)可能由不同应力状态下的剪切和开裂竞争所主导。针对这一问题,我们提出了一种新的、简明的 DBT 准则,即剪切-开裂(S-C)准则,它可以准确预测金属玻璃中由应力状态(外因)和泊松比(内因)变化引起的临界转变行为。此外,S-C 准则还能合理解释金属玻璃中拉伸断裂角在 60∘ 至 90∘ 范围内的罕见实验现象。重要的是,S-C 准则为从内在和外在因素提高金属玻璃的韧性提供了理论指导,从而促进了涉及金属玻璃的工程应用的发展。

Ductile-to-brittle transition criterion of metallic glasses

Ductile-to-brittle transition criterion of metallic glasses
In principle, the ductile-to-brittle transition (DBT) of metallic glasses may be dominated by the competition between shearing and cracking at different stress states. In response to this issue, we propose a new and concise criterion for DBT, named as the shearing-cracking (S-C) criterion, which can accurately predict the critical transition behaviors in metallic glasses induced by variations in both stress state (extrinsic factor) and Poisson's ratio (intrinsic factor). Furthermore, the S-C criterion provides a reasonable explanation for the peculiar phenomenon in metallic glasses that there are rare experimental cases of tensile fracture angle within the range of 60 to 90. Importantly, the S-C criterion offers theoretical guidance for toughness enhancement in metallic glasses from both intrinsic and extrinsic factors, thus facilitating the advancement of engineering applications involving metallic glasses.

期刊介绍: Physical Review Materials is a new broad-scope international journal for the multidisciplinary community engaged in research on materials. It is intended to fill a gap in the family of existing Physical Review journals that publish materials research. This field has grown rapidly in recent years and is increasingly being carried out in a way that transcends conventional subject boundaries. The journal was created to provide a common publication and reference source to the expanding community of physicists, materials scientists, chemists, engineers, and researchers in related disciplines that carry out high-quality original research in materials. It will share the same commitment to the high quality expected of all APS publications.
