The motion of line defects (dislocations) has been studied for more than 60 years, but the
maximum speed at which they can move is unresolved. Recent models and atomistic …

A three-dimensional discrete dislocation dynamics (DDD) method was used to investigate
the effect of residual stress on the stress-strain response of gradient nano-grained (GNG) …

This study deals with the evolution of strength and microstructure in Cu–20Ag alloy during
wire drawing from an initial diameter of 7.84 mm–0.02 mm. The final wire had a strength of …

The micro-cutting of brittle ceramics starts with elastic-plastic deformation followed by severe
brittle fracture, which significantly restricts the machinability and application of these …

The strain rate dislocation behavior in carbon nanotubes (CNTs) reinforcing aluminum is
described through an explicit, analytic grain interior/grain boundary affected zone (GI/GBAZ) …

Abstract Effects of strain rates on mechanical behaviors of nano-multilayered aluminum
5052 alloys are explored via molecular dynamics simulations. Yield strength and ultimate …

Additive manufacturing of pure copper (Cu) via laser-powder bed fusion (L-PBF) is
challenging due to the low energy absorptivity under infra-red laser. As a result, 3 …

Deformation at high strain rates often results in high stresses on many engineering
materials, potentially leading to catastrophic failure without proper design. High-strain-rate …

The method of Si substituting for Al was proposed to design a novel hot-rolled lightweight
steel with ultra-high ultimate tensile strength (2046 MPa) and good total elongation after …

Orowan strengthening is a key strengthening method for metallic materials. However, a
debate still exists on the effect of temperature on the Orowan strengthening mechanism …
