Influence of surface-roughness on indentation size effect

Acta Materialia, 2007
During nanoindentation of a material with a naturally rough-surface, a flattening of the rough-surface is additionally accomplished compared to nanoindentation on a flat surface. By separating analytically the work expended to flatten the rough-surface and to deform the flattened surface, we develop here a new rough-surface indentation size effect (ISE)

A Fractal Approach Interpretation for the Indentation Size Effect

2008
Since the 1950’s (Tabor [1]), the hardness measurements have been recognized to be size dependent; a hardness increase with decreasing indentation depth (or indenter size) is always observed. The indentation size effect (ISE) is extensively studied in the literature and research in this field has been continuously growing in the last decades; this is ...

Indentation size effect on the Fe2B/substrate interface

Surface and Coatings Technology, 2011
Abstract This study evaluated the indentation size effect on the Fe 2 B/substrate interface using the Berkovich nanoindentation technique. First, the Fe 2 B layers were obtained at the surface of AISI 1018 borided steels by the powder-pack boriding method.

Comment on “Indentation size effect: reality or artefact?”

Journal of Materials Science Letters, 1997
In a recently published work of Iost and Bigot [1] the geometrical model of Farges and Degout [2] proposed for the explanation of the indentation size effect (ISE) appearing in Vickers microindentation testing was supported by scanning confocal microscopy (SCM) measurements.
