Decoupling Stable Cyclic Deformation From Defect Accumulation in Metals [PDF]

Advanced science
Introducing amorphous nanoparticles into a metal matrix enables a cyclic deformation regime where strain hardening and defect accumulation are decoupled. These nanoparticles act as dislocation sinks and undergo reversible shear transformations, sustaining microstructural stability over millions of cycles.
