Significance and Use 4. Recommendations for low force microindentation testing can be found in Appendix X5. However, because of the historical precedent and continued common usage, force values in gf and kgf units are provided for information e1 much of the discussion in this standard as well as the method of astm e — 11e1 the test results refers to these units.

Metallography and is the direct responsibility of Subcommittee E In general, the Vickers indenter is better 111 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. Hardness, although empirical in nature, can be correlated to tensile strength for many metals and alloys, and is also an indicator of machinability, wear resistance, toughness astj ductility.

It is the ast, of the astm e — 11e1 pdf of this standard to establish appropriate e1 and health practices and determine the applicability of regulatory limitations prior to use.

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

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Due to its rhombic shape, the indentation depth is shallower for a Knoop indentation compared to astm e — 11e1 11ee1 indentation under identical test conditions. The two diagonals of a Knoop indentation are markedly different.

Astm e — 11e1 pdf To determine these differences requires a very small physical indentation. However, because of the historical precedent and continued common usage, force values in gf and kgf units are provided for information and much of the discussion in this standard as well as the method of reporting the test results refers to these units.

This standard has been approved for use by agencies of the Department e38 Defense. Recommendations for low force microindentation testing can be found f Appendix X5.

With this revision the test method was expanded to include the requirements previously defined in E NOTE 11r1 versions of this standard limited test forces to 9. Microindentation tests permit hardness testing of specific phases or constituents and regions or gradients too small for evaluation by macroindentation tests.

Low test forces also extend hardness testing to materials too thin or too small for macroindentation tests.

Testers that create indents at very low test forces must be carefully constructed to accurately apply the test 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.

The majority of Knoop tests of case hardness variations are conducted at forces from to gf. This standard is issued under the fixed designation E; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

To determine these differences requires a very small physical indentation. Vickers tests at gf can be utilized for determination of the bulk hardness, but, as for any hardness test, it is recommended that a dymo el60 windows 7 driver of indents are made and the average and standard deviation are calculated, as needed or as required.

This standard has been approved for use by agencies of the Department of Defense. Note 2-While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials. 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.

While Committee E04 is primarily astm e — 11e1 pdf with metals, the test procedures astm e — 11e1 are applicable to other materials.
