ClearHierarchy of the macrozone features in Ti-6Al-4V alloy inferred from massive polycrystal plasticity calculations
Researchers used advanced crystal plasticity computer modeling to study how clusters of similarly-oriented grains — called macrozones — affect stress concentrations and fatigue performance in titanium alloys used in aerospace applications. The term "microplastic" here refers to early-stage metal deformation behavior (not environmental plastic pollution); results showed macrozone texture and shape strongly influence where stress hotspots form under cyclic loading.
Slip Irreversibility, Microplasticity, and Fatigue Cracking Mechanism in Near-α and α + β Titanium Alloys
This paper is not about microplastics; it reviews the materials-science mechanisms of microplasticity, slip irreversibility, and fatigue crack initiation in near-α and α+β titanium alloys—a topic in metallurgy unrelated to plastic pollution.
In situ characterization of work hardening and springback in grade 2 α-titanium under tensile load
A study using X-ray diffraction and electron microscopy characterized work hardening and springback in titanium sheet metal. While unrelated to microplastics, research on mechanical behavior of metals is relevant to understanding how metal and polymer particles are generated during manufacturing and wear.
Effect of microvoids on microplasticity behavior of dual-phase titanium alloy under high cyclic loading (I): Crystal plasticity analysis
Researchers used crystal plasticity finite element modelling to investigate how microvoids influence microplasticity deformation in dual-phase titanium alloy under high cyclic loading. They found that geometrically necessary dislocations accumulate around microvoids, with void tip curvature having a greater effect on dislocation density than void size, and that increasing void size and curvature elevates cumulative shear strain across all phases.
