The conventional role played by precipitates in crystalline solids is in blocking the motion of
dislocations and for consequentially hardening, a mechanism attributed to Orowan's finding …

Pre-stretching is commonly employed to accelerate ageing precipitation kinetics in wrought
Al-Cu-Li alloys, but uneven precipitation resulting from dislocation pile-ups often degrades …

The age hardening response and tensile properties in an Al-Cu alloy pre-deformed by 20-
80% and post-aged at 120-165° C have been examined to study the effect of mixed …

Molecular dynamics (MD) shows a difference in the mechanisms of fracture of iron under
uniaxial and isotropic tension. Uniaxial tension leads to the formation of a complex …

We investigate the deformation of aluminum alloy containing copper in the form of fine Al-Cu
clusters 1–4 nm in diameter with multiscale approach. A part of these precipitates (clusters of …

We present molecular dynamics simulations of shock compression and spall fracture in [111]
copper single crystals with pre-existing dislocations. Shock waves are simulated for an …

Understanding dislocation behavior is considered an effective way to design high
performance alloys, as it is closely associated with mechanical properties. The existence of …

We develop the theory of homogeneous nucleation of dislocations, which predicts plasticity
incipience in FCC single crystal using material properties at elastic stage. In contrast to …

During hot deformation, continuous dynamic recrystallisation (CDRX) is believed to occur,
and even dominates microstructural evolution in many metallic materials with high stacking …

Molecular dynamics (MD) simulations are employed to study the interaction mechanisms
between dislocations and nano-precipitates in CuFe alloys. On one hand, the critical shear …
