Indentation Size Effect of Composite A356 + 6%FA Subjected to ECAP

Metals, 2022
In this study, metal matrix-based composite (MMC) was subjected to Equal Chanel Angular Pressing (ECAP) in several passes to determine the influence of deformation on the hardness of the samples. Composite based on A356 aluminum alloy and reinforced with

On the interpretation of the indentation size effect (ISE) through gradient theory for Vickers and Berkovich indenters

Journal of the Mechanical Behavior of Materials, 2016
The so-called indentation size effect (ISE) observed mainly in nanoindentation measurements with prismatic tips, is theoretically modeled in this article with the use of gradient theory. It is shown that the ISE, i.e.

A gradient elasticity approach to the indentation size effect at very small depths

Journal of the Mechanical Behavior of Materials, 2011
Over the past two decades, the indentation size effect (ISE) has been studied extensively by several authors. A common point among all these studies has been the premise that during the indentation process sufficient plastic deformation is developed so ...

Investigation of the mechanism of the indentation size effect for titanium

Mechanical Engineering Journal, 2019
In this study, we investigated the mechanism of the indentation size effect for Ti, whose crystal structure is hexagonal close-packed. Indentation tests were performed for two types of single-crystal Ti with different crystal orientations: (0001) and ...

Investigation of the indentation size effect based on measurement of the geometrically necessary dislocation density by electron backscatter diffraction

Mechanical Engineering Journal, 2018
In this study, we investigated the mechanism of the indentation size effect based on measurement of the geometrically necessary (GN) dislocation density. The GN dislocation density was measured around impressions by electron backscatter diffraction (EBSD)

INDENTATION SIZE EFFECT OF HEAT TREATED ALUMINUM ALLOY

Acta Metallurgica Slovaca, 2019
The aim of the submitted work is to study the influence of applied  loads ranging from 0.09807 N to 0.9807 N on measured values of micro-hardness of heat treated aluminum alloy 6082. The influence of applied load on a measured value of micro-hardness was

Nanoindentation of zirconium based bulk metallic glass and its nanomechanical properties

Journal of Materials Research and Technology, 2020
Nanoindentation experiments with a Berkovich tip are performed on zirconium based bulk metallic glass (Zr-BMG, Zr65Cu15Al10Ni10) to study its deformation and mechanical properties (elastic modulus and hardness) at nanoscale. Further to reveal indentation-
