On the Formation of Preferred Inclusion Shape Orientations in Copper‐Based Composites
AI summary Read the abstract
A three-component model of a copper-based composite under tensile loading was used to show how microplastic zone formation causes the composite to transition from isotropic to anisotropic mechanical behavior. The model calculates the effective elastoplastic moduli as a function of applied load and microplastic zone concentration, informing design of copper-matrix composites.
A three‐component model of copper‐based composite loaded by tensile forces is proposed. The effect of a nonhydrostatic stress state and the formation of microplastic zones cause the transition of the composite from an isotropic to an anisotropic state. We calculate the tensor of effective elastoplastic modulii of the model as a function of the applied load and of the microplastic zone concentration.

Experimental study and analysis of microplastic behavior of microheterogeneous metallic materials
AI summary Read the abstract
This experimental study investigated the microplastic deformation behavior of microheterogeneous metallic materials — alloys with a microstructure containing distinct phases or reinforcing particles. The work characterizes how microstructural heterogeneity influences the onset and distribution of small-scale plastic deformation prior to macroscopic yielding.
In Situ Observation of the Dislocation Structure Evolution During a Strain Path Change in Copper
AI summary Read the abstract
Researchers used high-energy synchrotron X-ray diffraction to observe in real time how dislocation structures in polycrystalline copper evolve when the direction of deformation is changed. It is a fundamental materials physics study using 'plasticity' in its metallurgical sense, unrelated to environmental microplastic research.
Transient Small-Scale Yield Behavior of Textured Copper Tubing Under Biaxial Loading
AI summary Read the abstract
Biaxial microplastic yielding in copper tubing was studied at room temperature following small prestrains in different stress directions to characterize time-dependent transient behavior. The results reveal how prior deformation history influences subsequent yield surfaces and the kinematic hardening behavior of copper at small plastic strains.
