Microhardness Anisotropy and the Indentation Size Effect (ISE) on the (100) of Single Crystal NiAl

MRS Proceedings, 2000
ABSTRACTThe Knoop microhardness anisotropy of single crystal NiAl, a B2 intermetallic compound, was investigated on the (001) plane at indentation test loads from 25 to 500 g. An energy balance analysis was applied to analyze the indentation size effect (ISE). The load independent, orientation independent Knoop microhardness was determined to be 220 kg/

The Indentation Size Effect (ISE) for Knoop Hardness in Five Ceramic Materials

, 2008
The variation of indentation hardness with contact load i.e., the indentation size effect (ISE), was investigated for five ceramic materials: (i) AlON, (ii) AD995 CAP3 Al 2 O 3 , (iii) pressureless-sintered SiC (Hexoloy SA), (iv) SiC-N, and (v) SiC-B. A Knoop diamond indenter was used to make indentations in the load range from 0.49 N (0.05 Kg) to 137 ...

Role of domain configurations on the mechanistic modelling of indentation size effects (ISE) in nanohardness of hard and soft PZT piezoceramics

International Journal of Advances in Engineering Sciences and Applied Mathematics, 2021
The intrinsic microstructural length scales of piezoelectric materials (e.g. grain size, nature of the domain and their orientations) spans from micron to nanoscale have a pronounced influence on the electromechanical behaviour. Of all these microstructural features, domain configurations particularly found to control the nanomechanical properties ...

A unified approach to quantify the material and geometrical effects in indentation size effect

Journal of Materials Research, 2023
The seminal work of Nix and Gao in (J Mech Phys Solids, 46:411–425, 1998), laid the foundation for quantifying indentation size effect (ISE). Several groups around the world have continued to explore the various factors that influence ISE, through ...

Indentation Size Effect Model of Ti6Al4V Alloy by Combining the Macroscopic Power‐Law Constitutive Relation and Strain Gradient Theory

Advanced Engineering Materials, 2022
Indentation size effect (ISE) is a critical feature for investigating the local properties of materials using the indentation test method. Although there are numerous works on the indentation response, there is a lack of data in the literature on the ...
