Nanoindentation in Metallic Glasses with Different Plasticity [PDF]

, 2015
Nanoindentation and thermomechanical experiments on three types of metallic glasses with different glass forming ability were carried out. The nanoindentation behaviour at room temperature was associated with the creep at elevated temperatures. Different

Bamboo‐Like Whiskers‐Reinforced Bioceramics Accelerate Large Segmental Bone Regeneration via Dual Modulation of Type‐H Vessels and Osteoinduction

Advanced Science, EarlyView.
The graphical abstract image of bamboo‐like whisker‐reinforced Ca‐P bioceramics accelerating large segmental bone regeneration. ABSTRACT Regenerative repair of segmental bone defect remains a major clinical challenge. The conventional mental implants suffer from mechanical strength mismatch and long‐term foreign bodies presence.

Nanoindentation of Gold Single Crystals

, 2004
Nanoindentation is an increasingly used tool to investigate the mechanical properties of very small volumes of material. Gold single crystals were chosen as a model system for surface modification studies, because of the electrochemical advantages and ...

A new approach of the Oliver and Pharr model to fit the unloading curve from instrumented indentation testing [PDF]

, 2017
The unloading part of a load–displacement curve from instrumented indentation tests is usually approximated by a power law (Oliver and Pharr model), where the load is the dependent variable. This approach generally fits well the data.

Solid Ethanol as a Renewable, Low‐Toxicity, Electron‐Beam Direct Write, and Biomedical Material

Advanced Science, EarlyView.
3D ice lithography (3DIL) enables the fabrication of intricate submicrometer objects using ethanol as a renewable starting material. This study combines process optimization, structural and material analysis, and biomedical applications, from cell culture scaffolds to the patterning of neurostimulation electrodes, demonstrating performance in both in ...

The Macroscopic Stress–Macroscopic Strain Relationship of the Hierarchical Honeycomb Nanoporous Materials by the Spherical Nanoindentation Simulation

Nanomaterials
The spherical nanoindentation macroscopic stress–macroscopic strain relationship of hierarchical honeycomb nanoporous material is defined by combining the spherical nanoindentation simulation and the uniaxial compression simulation. At the same time, the

Nanoindentation and Nanoscratch Behaviors of DLC Coatings on Different Steel Substrates

, 2005
Nanoindentation and nanoscratch tests were performed for diamond-like carbon (DLC) coatings on the different steel substrates in order to investigate the deformation and failure behaviors of the coating/substrate systems and their tribological properties.
