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 …

The influence of grain size on the flow stress of various FCC polycrystals (Cu, Al, Ag and Ni)
has been analyzed by means of computational homogenization of a representative volume …

Metal additive manufacturing (AM) provides an unprecedented opportunity to explore
extreme microstructural regimes and their associated effects on the mechanical response of …

The nonequilibrium statistical thermodynamics framework for thermally activated dislocation
ensembles introduced in Parts 1 and 2 is applied to interpret and explain the fraction of …

Plasticity of sub-micron scale metals is well known to be controlled by dislocation source.
Here, we report an in-situ study of how the dislocation structures generated by pre-strain in …

Grain size of metal phase and interphase property play an important role in enhancing the
strength-ductility synergy of graphene/metal nanocomposites. In this work, we propose a …

Grain refinement is an important mechanism to produce stronger alloys. Strain hardening is
an essential phenomenon in metal forming processes. The interaction between grain size …

Al/SiC composites are considered promising materials for electronic packaging and thermal
management systems, because of their high strength, low CTE, and high thermal …

Abstract The Hall–Petch relation has long been used to relate the yield strength of a metal to
its grain sizes in which the effectiveness of grain size strengthening in the metal is dictated …

Nanocrystalline silicon can have unique thermal transport and mechanical properties
governed by its constituent grain microstructure. Here, we use phonon ray-tracing and …
