Influence of Tempering Transformation Induced Plasticity (T-TRIP) on the Evolution of Residual Stresses in Laser Heat Treated 50CrMo4 Steel
Despite its title referencing "plasticity," this paper studies residual stresses in a type of industrial steel (50CrMo4) during laser heat treatment — not plastic pollution or microplastics. It examines how tempering transformation induced plasticity affects metal component stresses and is entirely outside the field of microplastic research.

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.
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.
