Materials often fail prematurely or catastrophically under load while containing voids, posing a challenge to materials manufacturing. We found that metal (gold) spherical voids with fraction of up 10% does not fracture in tension when the are shrunk submicron nanometer scale. Instead, dispersed nanovoids increase strength and ductility material simultaneously reducing its weight. Apart from suppressed stress strain concentration, such structure provides enormous surface area promotes...
A stable and strong nanoporous aluminum-alumina core-shell composite is self-organized in a galvanic replacement reaction.
The accuracy and reliability of small-scale mechanical tests remain doubtful due to significant dependence the obtained properties on specimen size. Mesoscale tensile with sizes ranging from 10 μm 1 mm are capable obtaining bulk-like but rarely applied hexagonal close-packed metals. In this study, well-designed comparative were carried out a Zircaloy-4 alloy grain size 4 using femtosecond laser-machined mesoscale specimens thickness about 60 μm, sub-sized 1.3 mm, standard mm. quantitative...
The kinematic and isotropic strain hardening was investigated in columnar-grained copper with preferentially oriented nanoscale twins deformed at two different rates of 5 × 10−5 10−3 s−1. A significant back stress is caused majorly by threading dislocation pile-up accumulation the grain boundaries rate independent. associated an increment local effective stems from storage twin boundaries, a high beneficial for enhancing tensile ductility.Impact statementLong-range detected to develop during...
We produced a 316L stainless steel with heterogeneous nanometer-thick lamellar structures by severe cold-rolling at room temperature, and conducted micro-scale tensile tests in different orientations to evaluate both the in-plane (parallel nano-lamellae) out-of-plane (normal 45° inclined mechanical anisotropy. The parallel orientation demonstrates greatest strength while exhibits least strength. normal directions also indicate significant transient elastic-plastic response due strain path...
