ClearEnhanced Fatigue Strength of Commercially Pure Ti Processed by Rotary Swaging
This materials science study found that processing commercially pure titanium by rotary swaging to refine its grain structure significantly improved its fatigue strength and resistance to crack growth. The research is focused on metal alloy engineering with no relevance to microplastic pollution.
Micro-Deformation and Fracture Features of Ti834 Titanium Alloy under Fatigue Loading
Researchers studied how titanium alloy responds to high-cycle fatigue loading versus dwell fatigue, identifying differences in deformation patterns at the microscale. Titanium alloys are used in environments where plastic corrosion byproducts can accelerate material degradation.
Hot Deformation Behavior and Processing Maps of a New Ti-6Al-2Nb-2Zr-0.4B Titanium Alloy
This materials science study characterized the high-temperature deformation behavior of a new titanium alloy used in aerospace and industrial applications. It has no direct relevance to microplastic or environmental health research.
Microstructure and Mechanical Properties of β-Titanium Ti-15Mo Alloy Produced by Combined Processing including ECAP-Conform and Drawing
Researchers processed medical metastable beta-titanium Ti-15Mo alloy through a combined severe plastic deformation route involving equal channel angular pressing-conform followed by drawing, studying the resulting microstructure and mechanical properties to assess this approach for enhancing the strength and fatigue performance of the alloy.
Adjusting the very high cycle fatigue properties of a metastable austenitic stainless steel by means of the martensite content
This metallurgy study examined how pre-deforming stainless steel to introduce martensite phase changes its fatigue properties under very high cycle loading. This is a materials engineering study on metal alloys with no relevance to environmental microplastics.
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.
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.
On Structural Sensitivity Of Young’s Modulus Of Ni-Rich Ti-Ni Alloy
This study explored how varying the initial microstructure and aging-induced precipitation in a Ni-rich Ti-50.8 at% Ni alloy modulates its Young's modulus over a wide range, providing guidance for tailoring implant materials to match the mechanical properties of bone.
Hierarchy 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.
Self-Heating and Fatigue Assessment of Laser Powder Bed Fusion NiTi Alloy with High Cycle Fatigue Mechanisms Identification
Researchers applied the self-heating method for the first time to laser powder bed fusion (LPBF) NiTi alloys, testing two loading ratios to rapidly assess fatigue properties. The study identified key high-cycle fatigue mechanisms including intra-grain misorientation, persistent slip band growth, and stress-induced martensite formation.

This study examined how grain size and heat treatment affect Young's modulus in nickel-rich titanium-nickel alloy for bone implant applications. This is a materials science paper focused on biomedical alloys with no direct relevance to microplastics or environmental health.

Researchers tested an impact-oscillation method for improving the mechanical properties of high-strength titanium alloy sheets. This is a metallurgical engineering paper unrelated to environmental microplastics.
A Study of Thermal Stability of Residual Stresses and Fatigue life of Laser Shock Peened Ti-6Al-2Sn-4Zr-2Mo alloy
This aerospace engineering study examined how laser shock peening—a process that introduces compressive stress into metal surfaces—affects the fatigue life and thermal stability of a titanium alloy used in high-temperature aerospace applications. This is a materials engineering study with no relevance to microplastic pollution.
Determination of energy dissipation during cyclic loading and its use to predict fatigue life of metal alloys
This paper is not about microplastics — it develops a mathematical method for predicting the fatigue life of metal alloys from energy dissipation during cyclic loading.
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.
