Metallic glasses: Elastically stiff yet flowing at any stress
Researchers demonstrated that metallic glass, an amorphous solid with high yield stress, lacks a true microscopic elastic limit. Using coherent X-ray scattering, they found that even extremely small stresses accelerate atomic-scale transport within the material. The findings reveal fundamental differences in how amorphous and crystalline solids respond to mechanical stress at the atomic level.
From Micro‐ to Macroplasticity
This materials science perspective discusses the transition from microplastic deformation (below the yield stress) to macroplastic deformation in nanocrystalline metals, noting that the traditional 0.2% yield stress definition does not accurately capture when bulk plastic flow begins. This is a materials physics study on metal deformation behavior with no relevance to environmental microplastics.
Stress breaks universal aging behavior in a metallic glass
Researchers discovered that applying mechanical stress to metallic glass — an amorphous, non-crystalline metal — disrupts the material's predictable aging behavior by triggering localized microscale plastic deformation events (called microplastic events) that cause irregular, unpredictable changes in the material's internal structure. This finding challenges a long-standing universal model used to predict how metallic glasses behave under stress over time.
