ClearCrystal plasticity in fusion zone of a hybrid laser welded Al alloys joint: From nanoscale to macroscale
This materials science study examined the plasticity of hybrid laser-welded aluminum alloy joints from the nanoscale to the macroscale, developing models based on micropillar compression tests. It is focused on structural materials science rather than environmental plastic pollution.
About Wave Nature of the Formation of Gradient and Microcomposite Zones Near Non-Metallic Inclusions During Laser Processing of the Steels
This paper is not relevant to microplastics research — it investigates the wave-based formation of gradient and composite zones near non-metallic inclusions during laser processing of steel.
Role of Grain Boundary Sliding in Texture Evolution for Nanoplasticity
This materials science paper presents a crystal plasticity model for how grain boundary sliding affects texture evolution in nanocrystalline metals under large deformation. It is a technical metallurgy study with no connection to microplastics or environmental health.
Effect of Laser Shock Peening on the Microstructure and Properties of the Inconel 625 Surface Layer
Researchers investigated how laser shock peening affects the microstructure and mechanical properties of a high-performance nickel alloy. While unrelated to microplastics directly, understanding metal alloy behavior under stress is relevant to designing durable infrastructure that resists the mechanical wear that generates metal and polymer particles.
Revealing Grain Boundary Sliding from Textures of a Deformed Nanocrystalline Pd–Au Alloy
This materials science paper presents a model for understanding grain boundary sliding in nanocrystalline metals using crystallographic texture analysis. It is a technical metallurgy study with no direct connection to microplastics or environmental health.
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. While focused on materials science, understanding plastic deformation in amorphous metals contributes to developing more durable engineered materials.
Viscosity 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.
Dislocation-mediated relaxation in nanograined columnar palladium films revealed by on-chip time-resolved HRTEM testing
Time-resolved electron microscopy of nanograined palladium films revealed unexpectedly large creep rates at room temperature, caused by dislocation movement at tiny grain boundaries. This nanomaterials science study addresses deformation in thin metallic films and has no relevance to microplastics research.
Quantifying Co-Deformation Effects in Metallic Laminates by Loading–Unloading–Reloading Tensile Tests
This paper is not about microplastics; it investigates the mechanical co-deformation behavior of metallic laminate materials using cyclic tensile loading tests.
Rapid Fatigue Limit Estimation of Metallic Materials Using Thermography-Based Approach
This paper is not about environmental microplastics; it uses the term "microplastic" in a materials science context to describe microscopic plastic deformation in metals during fatigue testing.
Slip localization and grain boundary sliding analysis at sub-voxel resolution using phase contrast tomography
Researchers used phase contrast tomography and laser confocal microscopy to analyze microplasticity events—slip, twinning, grain boundary sliding—on the surface of a nickel-based superalloy at room temperature and 650°C. Despite slip amplitudes smaller than the imaging voxel size, the technique successfully resolved out-of-plane kinematics, demonstrating its value for studying sub-voxel deformation.
Variety of scaling behaviors in nanocrystalline plasticity
This is a materials science study examining the variety of scaling behaviors observed in nanocrystalline plasticity, exploring how grain size affects deformation mechanisms in metals. It is not related to environmental microplastics.
Dislocation Patterning in Deforming Crystals: Theory, Computational Predictions and Validation (Final Technical Report)
This technical report covers a multi-year project on how dislocations — microscopic defects in metal crystals — form patterns during deformation. The research advances fundamental materials science relevant to metal manufacturing and is not directly related to microplastics or environmental health.
