A ductility criterion for bcc high entropy alloys

William Curtin, Binglun Yin, Eleanor Yi Kei Mak

A current goal driving alloy development is the identification of alloy compositions for high temperature applications but with the additional requirement of sufficient ductility at ambient temperatures. Multicomponent, single-phase, polycrystalline High E ...

Fault Stability Across the Seismogenic Zone

François Xavier Thibault Passelègue

Across the seismogenic zone, the transition from brittle to plastic deformation corresponds to a semibrittle regime where brittle fracturing and plastic flow coexist at high strength conditions. Thorough experimental investigations on brittle-plastic trans ...

Out-of-plane (flatwise) behavior of through-tenon connections using the integral mechanical attachment technique

Yves Weinand, Aryan Rezaei Rad

This paper aims to characterize the force–deformation response of through-tenon wood-wood connections subjected to out-of-plane (flatwise) loads. Six beech LVL timber specimen groups with variations in the fiber orientation (parallel and perpendicular) and ...

Dynamic study of contact damping in martensitic stainless steels using nano-indentation

Philippe Spätig, Hans-Peter Seifert

The study was undertaken to gain insight into the micro-mechanisms controlling plasticity at the micrometer scale of elastic-plastic metallic alloys. Dynamic nano-indentation tests, where a small harmonic force amplitude is superimposed during loading, ref ...

Meso-scale modelling of ASR in concrete: effect of viscoelasticity

Jean-François Molinari, Mauro Corrado, Emil Gallyamov, Roozbeh Rezakhani

A meso-scale numerical model for simulating damage in concrete due to ASR is presented. It accounts for the internal structure of concrete including aggregates and mortar. ASR sites are explicitly represented. This model is extended to account for viscoela ...

Structural Phase Transition and Bandgap Control through Mechanical Deformation in Layered Semiconductors 1T-ZrX2 (X = S, Se)

Helmuth Berger, Oleg Yazyev, Ana Akrap, Edoardo Martino, Michele Pizzochero, Kristians Cernevics, Konstantin Semeniuk

Applying elastic deformation can tune a material's physical properties locally and reversibly. Spatially modulated lattice deformation can create a bandgap gradient, favoring photogenerated charge separation and collection in optoelectronic devices. These ...

Deformation mechanisms in a superelastic NiTi alloy: An in-situ high resolution digital image correlation study

Helena Van Swygenhoven

An in-situ high resolution digital image correlation investigation during uniaxial tensile deformation reveals the recoverable and the non-recoverable strain mechanisms in a Ni51Ti49 alloy with a mean grain size of 35 mu m. Recoverable strain is due to the ...

Annealing hardening and softening of an ultrafine grained Cu-4.5vol.% Al2O3 nanocomposite

Roland Logé, Jun Wang

Samples from an ultrafine-grained Cu-4.5vol.%Al2O3 nanocomposite rod fabricated by powder compact extrusion were annealed at 400 and 700 degrees C for 15 min respectively, and their microstructure and mechanical properties were investigated. It shows that ...
