Micro-and nanomechanical testing has seen a rapid development over the last decade with
miniaturized test rigs and MEMS-based devices providing access to the mechanical …

The interactions between dislocations (dislocations and deformation twins) and boundaries
(grain boundaries, twin boundaries and phase interfaces) during deformation at ambient …

Architected materials that consist of periodic arrangements of nodes and struts are
lightweight and can exhibit combinations of properties (such as negative Poisson ratios) that …

We designed micromechanical experiments to examine the deformation behaviors of
austenitic stainless steels fabricated by additive manufacturing. Micro-pillars containing …

In this work, a new dual-phase high-entropy alloy (HEA) coating is successfully synthesized
by laser cladding. XRD, SEM, TEM, EBSD, and TG-DSC are employed to investigate the …

Grain boundaries (GBs) have a significant influence on the mechanical properties of metallic
materials. It has been a great challenge to describe dislocation interactions with various …

To understand the underlying mechanisms that control the mechanical properties of
nanostructured metals, an insight into the role of the grain boundary in dislocation-driven …

To overcome the Hydrogen embrittlement (HE) susceptibility of the standard Alloy 725 (Mod
A), two alloys with minor alloying modifications with B (Mod B) and B+ Cu (Mod C) were …

We investigated the effects of the grain size on the yield strength of aluminum using a group
of samples with grains successively refined by equal-channel angular pressing (ECAP) and …

Twin boundaries (TBs) constitute a special type of symmetric grain boundary (GB). TBs
influence plastic deformation in a complex manner. They not only act as dislocation …
