For most metallic materials, surface hardening via modifying the near-surface microstructure
is an effective method for improving mechanical properties. Among these processes, laser …

Overcoming the trade-off between strength and ductility in metallic materials is a grand
challenge. Recently, materials with a gradient nano-grained (GNG) surface layer adhering to …

Additively Manufactured (AM) metallic alloys differ from their conventionally produced
counterparts by complex multi-scaled microstructures leading to deeply modified …

Mixed-grain structure with millimeter-grade coarse grains (MCGs) is an intolerable defect
often found in heavy forgings. Eliminating this microstructural defect through …

Electrically assisted (EA) forming has ubiquitous merits over room-temperature (RT) forming
and thermally aided forming for the fabrication of difficult-to-form microscale products …

Flow stress and work hardening behaviors, as two important aspects of mechanical
behaviors, have been studied extensively and their interpretation for the case of pure metals …

Revisiting the classical topic of the strain hardening behaviour from a perspective of the
analytical model based on the evolution of dislocation density with strain, we extended the …

Here, a new strategy, ie, laser shock peening (LSP) followed by cyclic deep cryogenic
treatment (DCT), is proposed to generate the gradient hierarchical structures and thus …

In the present work, we propose a novel model coupling phase-field, dislocation density
based plasticity and damage. The dislocation density governing equations are constructed …

The microstructure evolution and strengthening mechanism of materials after shot peening
have always been the focus of research. In this paper, a novel coupled constitutive model …
