Hardness Indentation Studies On Metallic Glasses
MRS Proceedings, 2002ABSTRACTVickers micro-hardness indentations have been performed on a number of amorphous metals. The effects of changes in indentation load on the hardness and appearance of indents will be discussed for amorphous Al87Ni7Gd6. In addition, the effects of changes in test temperature on the micro-hardness and appearance of indentations in Vitreloy I are ...

Elastic‐Plastic Indentation of Hard, Brittle Materials with Spherical Indenters
Journal of the American Ceramic Society, 1994A method was developed at the U.S. Bureau of Mines to measure the plastic deformation of hard, brittle materials with low values of elastic modulus to hardness (E/H). The method involves indenting the hard materials with spherical indenters and measuring the resulting contact diameter and depth.

Indentation Hardness of Surface-Coated Materials
1985A model for the mechanical interaction between a deposited surface film and its substrate during indentation is investigated for a number of material combinations. Linear relationships between the indentation microhardness and the inverse of the indentation diagonal are found for indentations larger than a limiting size, for both coated and uncoated ...

PROGRESS IN MICRO-INDENTATION HARDNESS TESTING
Metallurgical Reviews, 1959AbstractAs the concept of micro-indentation hardness testing has not yet become commonly accepted, nor has any definition of it been universally agreed upon, it is desirable to begin by reviewing the development and the present state of hardness testing under low load, and to say something about the terminology.

Influence of the indenter shape in Rockwell Hardness Test
1998One of the main problems related to Rockwell hardness measurements is the influence of the indenter shape. In the present work the effects of the macro-geometry of the diamond indenter are analyzed as influencing parameters in Rockwell C test. Both an experimental analysis is carried out, using IMGC National Standard Machine, and a finite element ...
