Analysis of the Subsurface Volume of Differently Finished AISI 52100 by Cyclic Indentation and X‐Ray Diffraction
This study analyzed how different surface finishing processes affect fatigue behavior in roller bearing steel, finding that surface roughness and residual stress influence component lifetime. The research is focused on materials engineering and has limited direct relevance to microplastic pollution.
Material Response to Rolling Contact Loading
This materials science study investigates how rolling contact in ball bearings causes microplastic deformation in steel, leading to crystallographic texture changes, residual stresses, and eventual fatigue failure. The term 'microplastic' in this paper refers to small-scale plastic deformation in metals and has no connection to environmental plastic pollution.
The effects of oil-quenching and over-tempering heat treatments on the dry sliding wear behaviours of 25CrMo4 steel
Researchers tested how different heat treatments affect the wear resistance of 25CrMo4 steel used in automotive parts, finding that oil-quenching and over-tempering significantly reduced material wear loss compared to untreated steel, even when hardness slightly decreased — important for extending the life of industrial components.
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.
Optimize Multiple Peening Effects on Surface Integrity and Microhardness of Aluminum Alloy Induced by LSP
Researchers investigated multiple laser shock peening (LSP) treatments on aluminum alloy specimens, measuring effects on surface integrity, microhardness, and mechanical properties and finding that optimized multi-pass LSP improved fatigue resistance and surface uniformity compared to single-pass treatment.
Surface Residual Stress Release Behavior of Shot-Peened Springs
Researchers developed an equivalent replacement algorithm to quantify residual stress reduction in shot-peened springs under cyclic multiaxial loading, accounting for surface roughness, helix angle, and cyclic loading effects on stress attenuation. They found that the algorithm accurately modeled dynamic residual stress release and that incorporating it into a spring fatigue life prediction model improved estimation accuracy.
Adjusting the very high cycle fatigue properties of a metastable austenitic stainless steel by means of the martensite content
