ClearModification of the Structural, Microstructural, and Elastoplastic Properties of Aluminum Wires after Operation
Structural and microstructural changes in aluminum wires from overhead power transmission lines of 0 to 62 years service life were characterized using X-ray diffraction and electron backscatter diffraction, finding progressive work hardening and grain boundary changes that affect wire strength and longevity.
Structural, Microstructural, Elastic, and Microplastic Properties of Aluminum Wires (from AAAC (A50) Cables) after Fatigue Tests
Researchers characterized the structural, microstructural, elastic, and microplastic deformation properties of aluminum wires from AAAC (A50) overhead power line cables after laboratory fatigue testing, using X-ray diffraction, electron backscatter diffraction, densitometry, and acoustic methods to identify degradation patterns relevant to predicting cable lifespan.
Comparison of Structural, Microstructural, Elastic, and Microplastic Properties of the AAAC (A50) and ACSR (AC50/8) Cables after Various Operation Periods in Power Transmission Lines
This study compared the structural and mechanical properties of aluminum cables used in overhead power transmission lines after different periods of operation. Both all-aluminum alloy and aluminum-steel reinforced cable types were tested for hardness, elastic modulus, and microstructural changes with age. Understanding cable degradation is important for maintaining safe and reliable electrical infrastructure.

In situ fragmentation of Al/Al2O3 multilayers on flexible substrates in biaxial tension
Researchers studied how thin layers of aluminum and aluminum oxide stacked on flexible plastic substrates behave when stretched, finding that thinner oxide layers prevent brittle cracking and improve the material's resistance to damage. Understanding how these multilayer coatings fail under stress is important for designing more durable flexible electronics and packaging materials.

This study examined how heterogeneous multilayer metal composites resist fracture under dynamic and cyclic loading, finding that layer boundaries retard crack propagation compared to homogeneous materials. The findings are relevant to materials engineering for durable structures, though not directly related to microplastic research.
Fatigue Damage Evaluation of Aviation Aluminum Alloy Based on Strain Monitoring
Researchers developed a metal fatigue damage model for aerospace aluminum alloy using real-time strain monitoring combined with crystal plasticity finite element analysis, establishing a constitutive relationship between strain and damage prior to microcrack initiation. Electron backscatter diffraction analysis validated the model's accuracy in predicting fatigue damage states under various stress conditions.
Durability and Additional Properties of Anodized Aluminum-Based Coatings with Different Wettability under Natural Conditions
Long-term outdoor testing of anodized aluminum coatings with varying hydrophobicity found that superhydrophobic coatings maintained their self-cleaning and anti-corrosion properties through outdoor exposure but lost anti-icing properties, while hydrophilic coatings showed consistent but lower performance.
Влияние структурного состояния на упругие и микропластические свойства алюминиевого сплава AД1
This Russian-language study examined how different processing methods affecting the crystal grain structure of aluminum alloy AD1 influence its elastic and 'microplastic' deformation properties. 'Microplastic' here refers to microscopic metal deformation — this is a materials engineering study unrelated to plastic particle pollution.

Influence of structural and physical degradation of the stressed metal of pipes on the damage of main gas pipelines
Researchers examined the mechanisms by which structural and physical degradation of stressed pipeline metal contributes to stress corrosion cracking in main gas pipelines, analysing regulatory approaches and diagnostic methods. They found that hydrogen concentrating in near-surface metal layers — facilitated by tensile stresses — promotes microplastic deformations that intensify crack propagation, identifying surface layer defects as the primary driver of corrosion-mechanical failure.
