ClearViscosity and transport in a model fragile metallic glass
This paper uses the term 'microplasticity' in the context of metallic glass physics, describing how thermally activated atomic movements drive deformation in amorphous metals at the microscale. This is a materials physics paper unrelated to environmental microplastic pollution.

Elasto-plastic behavior of amorphous materials: a brief review
This materials science review discusses how disordered (amorphous) materials like metallic and silicate glasses deform plastically at the atomic scale, focusing on localized shear band formation. The term 'plasticity' here refers to material deformation behavior, not environmental plastic particles.
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.

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.

Rejuvenation engineering in metallic glasses by complementary stress and structure modulation
Researchers used X-ray diffraction to study how stress and structural rejuvenation affect the mechanical properties of metallic glasses at a microscale.

Structural changes in a metallic glass under cyclic indentation
Researchers used computer simulations to study how a metallic glass material — a disordered metal alloy — changes at the atomic level when repeatedly pressed with an indenter, finding that the material initially relaxes structurally but then gradually rebuilds its original structure, explaining the known phenomenon of metals getting harder with repeated deformation cycles.
