Solid phase processing (SPP) is a promising alloy fabrication technique to produce fine and
homogeneous grain structures for high-performance alloys. However, there is very limited …

The evolutions of nano-twins and martensitic transformation in 316L austenitic stainless
steel during large tensile deformation were studied by electron backscatter diffraction …

Sliver is a common but easily neglected defect in single crystal Ni-based superalloy
castings. To date, there is still no unified viewpoint on its formation mechanism and …

The objective of the current work is to establish, on the one hand, the conventional
mechanisms of grain refining and, on the other hand, the effect of the refining-modification …

The grain structure of metals changes significantly during severe plastic deformation (SPD),
and grain refinement is the main process associated with SPD at low homologous …

Abstract Copper-Graphene (Cu-Gr) composites demonstrate high strength, lubricity, and
enhanced electrical and thermal conductivity compared to pure copper. A homogeneous …

Deformation processing of immiscible systems is observed to disrupt thermodynamic
equilibrium, often resulting in nonequilibrium microstructures. The microstructural changes …

Ultrafine-grained (UFG) tungsten heavy alloys possess potential applications in precision
instruments and nuclear protection. In the present study, a comprehensive investigation of …

Tens-nanometer sized defect substructures such as dislocation network, nanotwin and new
grain or phase may form during solid phase processing (SPP), which affect the energy …

Molecular dynamics (MD) simulations are used to reveal the mechanisms of defect
substructure evolution and atomic mixing in nanocrystalline Cu/Ni composites under severe …
