ASTM E384:11e1

Low test forces also extend hardness testing to materials too thin or too small for macroindentation tests. Microindentation hardness tests also allow specific phases or constituents and regions or gradients too small for macroindentation hardness testing to be evaluated. The success of the specimen preparation procedure in removing preparation-induced damage can, and will, influence test results; this problem becomes more critical as the test force decreases.

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. Last previous edition approved in as E — 10e2.

If the test is being conducted to meet a specified bulk hardness value, such as HRC, then most such tests will be conducted with Knoop at a gf load.

With this revision the test method f384 expanded to include the requirements previously defined in E In general, the Vickers indenter is better suited for determining bulk average properties as Vickers hardness is not altered by the d of the test force, from 25 to gf, because the indent geometry is constant as a r384 of indent depth. It is the responsibility of the user of this standard atsm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior aztm use.

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 atsm units.

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. While Committee E04 is primarily concerned with metals, the test procedures described are applicable to other materials. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not asgm as part of the standard.

Due to its rhombic shape, asrm indentation depth is shallower for a Knoop indentation compared to a Vickers indentation under identical test conditions. This standard is also available to be included in Standards Subscriptions. Thus, the Knoop indenter is very useful for evaluating hardness gradients or thin coatings of sectioned samples.
