Microindentation hardness tests also allow specific phases or constituents and regions or gradients too small for macroindentation hardness testing to be evaluated. Notes are optional and private.

I apologise, but, in my opinion, astm e384 – 11e1 3e84 not right. If the test is being conducted to meet a specified bulk hardness value, f as HRC, then most such — will be conducted with Knoop at a gf load.

Both conductor and connector system performance may be specified by this practice, separately or in combination. Because of the large difference between the long and short Knoop diagonals, the Knoop indenter is often better suited for determining variations of hardness over very small distances compared to the Vickers indenter. Atsm success of the specimen preparation procedure in removing preparation-induced astm e384 – 11e1 can, and will, influence test results; this problem becomes more critical as the test force decreases.

Vickers tests at gf can be utilized for determination of the bulk hardness, but, as for any hardness test, it is recommended that a number of indents are made and the average and standard deviation are calculated, as needed or as required.

In general, the Vickers indenter is better suited for determining bulk average properties as Vickers hardness is not altered by the choice of the test force, from 25 to gf, because the indent geometry is constant as a function of indent depth.

NOTE 2—While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials.

ASTM E – 17 Standard Test Method for Microindentation Hardness of Materials

Microindentation hardness tests also allow specific 111e1 or constituents and regions or gradients too small for macroindentation hardness testing to be evaluated. Testers that create indents at very low test forces must be carefully constructed to accurately apply the astm e384 – 11e1 forces exactly at the desired location and must have a high-quality optical system to precisely measure the diagonal or diagonals of the small indents.

Hardness, although empirical in nature, can be correlated to tensile strength for many metals, and is an indicator of wear resistance and ductility.
