ClearEffects of plastic strain and reloading stress on the magneto-mechanical behavior of electrical steels: Experiments and modeling
Researchers studied how bending and stretching steel during manufacturing permanently changes its magnetic properties, finding that plastic deformation degrades magnetic performance but applying tension afterward can partially restore it. They developed a model that accurately predicts these magnetic changes, which could help engineers better design electric motors and transformers.
Effects of Pulsed Magnetic Fields of Different Intensities on Dislocation Density, Residual Stress, and Hardness of Cr4Mo4V Steel
This paper studied how pulsed magnetic fields affect the internal stress and hardness of a bearing steel alloy. While unrelated to microplastics, research on material durability is relevant to reducing wear-generated particles from industrial machinery, which can contribute to microplastic and metal particle pollution.
A Study of Stress – Induced Subtle Magnetic Changes in a Mild Steel using Barkhausen Emission-Aided Analysis Approaches
Researchers used magnetic Barkhausen emission analysis to detect subtle stress-induced changes in the magnetic properties of mild steel. They found that elastic stress caused both quantitative changes in domain wall activity and qualitative shifts in domain wall motion. This non-destructive approach could improve structural health monitoring in steel-based infrastructure.
Influence of the Loading Frequency on Very High Cycle Fatigue Behavior of Structural Steels
This study examined how loading frequency affects very high cycle fatigue behavior in two structural steels, finding that microplasticity strain amplitude decreased by an order of magnitude at ultrasonic frequencies, with cyclic strain rate being the key factor explaining frequency effects.
Research Progress of Magnetic Field Regulated Mechanical Property of Solid Metal Materials
This review summarizes research on magnetic field-assisted processing of solid metal materials, showing that applied magnetic fields can non-contactually alter microstructure and improve mechanical properties of difficult-to-deform metals without changing their shape or dimensions.
The quantitative relationship between non-linear stress-strain behaviour and dislocation structure in martensitic stainless steel
Researchers showed that martensitic stainless steel behaves in a more complex, non-linear way at low stresses than previously assumed, and developed a refined model to quantify tiny reversible deformations caused by dislocation movement, with implications for precision industrial applications where small strains matter.
Effects of Electric and Magnetic Treatments on Microstructures of Solid Metals: A Review
Researchers reviewed how applying electric or magnetic fields to solid metals can alter their internal structure — including how crystals form, how defects move, and how phases transform — in ways that traditional heat treatments cannot achieve. These electromagnetic processing techniques offer new possibilities for improving the strength and properties of metal alloys during manufacturing.
Microstructural behavior of magnetorheological elastomer undergoing durability evaluation by stress relaxation
This materials engineering study examined the stress relaxation behavior of magnetorheological elastomers—rubber-like materials embedded with magnetic particles—under long-term loading. The findings help predict how these specialty materials degrade over time in vibration-damping applications in vehicles and industrial machinery.
Transformation Kinetics, Microplasticity and Aging of Martensite in FE-31 Ni.
This materials science study examines microplastic behavior in iron-nickel martensite alloys, finding that stress-induced phase transformation produces unusually large microplastic strains. The term 'microplasticity' refers to small-scale plastic deformation in metals and is not related to environmental plastic pollution.
Exploring the effect of complex hierarchic microstructure of quenched and partitioned martensitic stainless steels on their high cycle fatigue behaviour
Not relevant to microplastics — this paper investigates high cycle fatigue behavior of quenched-and-partitioned martensitic stainless steels, exploring how their complex retained-austenite microstructure affects fatigue fracture performance.
On Microplasticity-induced Fatigue Fracture and its Relation to Entropy
Researchers investigated the relationship between microplasticity and fatigue fracture in steel specimens under axial cyclic loading, using fatigue testing machines to identify the stress cycle point at which microplastic deformation becomes detectable and analyzing its relationship to entropy production.
