Anisotropic Deformation Behavior and Indentation Size Effect of Monocrystalline BaF₂ Using Nanoindentation. [PDF]

Materials (Basel), 2023
In this study, our objective is to investigate the anisotropic deformation behavior and the indentation size effect (ISE) of monocrystalline barium fluoride (BaF2) using nanoindentation experiments with a diamond Berkovich indenter. BaF2 is known for its

Microhardness, Indentation Size Effect and Real Hardness of Plastically Deformed Austenitic Hadfield Steel. [PDF]

Materials (Basel), 2023
Microhardness testing is a widely used method for measuring the hardness property of small-scale materials. However, pronounced indentation size effect (ISE) causes uncertainties when the method is used to estimate the real hardness. In this paper, three

The relationship between the deformation and the indentation size effect (ISE)

Metallurgical Research & Technology, 2019
The aim of the submitted work is to study the relationship between the local deformation and the indentation size effect (ISE). A local value of reduction of the area (Z) was used as the measure of the deformation.

Effect of Strain Rate on Nano-Scale Mechanical Behavior of A-Plane ($11\overline{2}0$) ZnO Single Crystal by Nanoindentation [PDF]

Micromachines, 2023
In this study, nanoindentation tests at three different strain rates within 100 nm indentation depth were conducted on an a-plane (112¯0) ZnO single crystal to investigate the effect of strain rate on its nano-scale mechanical behavior.

Detection of the indentation-size-effect (ISE) and surface hardening by analysis of the loading curvature C

International Journal of Solids and Structures, 2016
Abstract Numerous materials are affected by the Indentation-Size-Effect (ISE). Thus, the interpretation of ISE-influenced indentation data plays an important role. This paper presents a method which allows for the characterization of the ISE using the loading curvature C of a single load-displacement curve (P–h curve) from sharp indentation.

Load-Independent Hardness and Indentation Size Effect in Iron Aluminides. [PDF]

Materials (Basel)
In this paper, an iron–aluminide intermetallic compound with cerium addition was subjected to Vickers microhardness testing. A full range of Vickers microhardness loadings was applied: 10, 25, 50, 100, 200, 300, 500, and 1000 g.

Investigation of indentation size effect (ISE) and micro-mechanical properties of Lu added Bi2Sr2CaCu2Oy ceramic superconductors

Journal of Materials Science: Materials in Electronics, 2012
In this study, we investigated the effect of the Lutetium (Lu) addition on microstructure and mechanical properties of the Bi-2212 superconductors annealed at 840 °C for 50 h. The samples were prepared by the widely used conventional solid-state reaction method. For comparison, undoped sample was prepared in the same conditions.

The indentation size effect of single-crystalline tungsten revisited [PDF]

Journal of Materials Research, 2021
In this study, we have investigated the indentation size effect (ISE) of single crystalline tungsten with low defect density. As expected, the hardness shows a pronounced increase with decreasing indentation depth as well as a strong strain rate ...

Analysis of indentation size effect (ISE) behavior in low-load Vickers microhardness testing of (Sm123)1−x(Nd123)x superconductor system

Journal of Materials Science: Materials in Electronics, 2013
Indentation size effect (ISE) for (Sm123)1−x(Nd123)x superconducting samples which were fabricated by the solid state reaction technique for values of x = 0.00, 0.05, 0.10, 0.20, and 0.30 was investigated by analyzing the theoretical models. When the experimental data of a number of single crystals which have the different crystal structure and ...
