Indentation size effect and hardness of materials [PDF]
E3S Web of Conferences, 2023 In recent decades, the Indentation Size Effect (ISE), which manifests itself as a change in fixed hardness depending on indentation conditions, has become one of the most urgent problems of modern materials science.

The influence of indenter tip rounding on the indentation size effect [PDF]
Acta Materialia, 2010 A model was developed to interpret the indentation size effect. The model considers the tip wear effect, causing a rounded tip, the plastic zone size and various strengthening contributions, including geometrically necessary dislocations, preexisting ...

Shear-banding Induced Indentation Size Effect in Metallic Glasses. [PDF]
Sci Rep, 2016 AbstractShear-banding is commonly regarded as the “plasticity carrier” of metallic glasses (MGs), which usually causes severe strain localization and catastrophic failure if unhindered. However, through the use of the high-throughput dynamic nanoindentation technique, here we reveal that nano-scale shear-banding in different MGs evolves from a ...

On the novel finding of two modified-Nix-Gao models for indentation size effect [PDF]
Scientific ReportsExisting modified-Nix-Gao models have been developed to accurately describe the descending indentation size effect (ISE). This raises the question of whether the modified-Nix-Gao models can describe other types of ISE. In this paper, because Nix-Gao-Feng

Effect of temperature and strain rate on indentation size effect at shallow indentation depths
Materials & DesignThis study investigates the indentation size effect in a bcc silicon iron single-crystal tested at different temperatures and strain rates. The classical Nix-Gao model based on strain gradient plasticity and geometrically necessary dislocations starts to

Hardness-Depth Relationship with Temperature Effect for Single Crystals—A Theoretical Analysis
Crystals, 2020 In this paper, a mechanistic model is developed to address the effect of temperature on the hardness-depth relationship of single crystals. Two fundamental hardening mechanisms are considered in the hardness model, including the temperature dependent ...
