WebMicroindentation hardness testing, more com- monly (but incorrectly) called microhardness testing, is widely used to study fine scale changes in hardness, either intentional or …

WebMicroindentation hardness is a measure of machinability, wear resistance, toughness, and ductility in metals. Test Procedure: For ASTM E384, a Knoop or Vickers indenter made from diamond is impressed into the test specimen at loads from a few grams to 1 kilogram. WebNov 24, 2024 · What is ASTM E384-22?. The test method in ASTM E384-22 covers determination of the microindentation hardness of materials, which involves using a calibrated machine to force a diamond indenter of specific geometry into the surface of the material being evaluated. This test method is largely applicable to heat treaters, …

WebMicroindentation hardness numbers depend on a combination of surface and bulk material properties. As indenter geometry and test loads are changed (particularly at loads below about 100 g), different combinations of surface and bulk properties may contribute to the net response of the material.
