Standard Test Method 51: Method for Determination of Microindentation Hardness of Powder Metallurgy Materials

This standard covers the determination of the micro-indentation hardness of PM materials. The procedure differs from that applied to pore-free material in terms of the precautions required to deal with the porosity. This procedure covers tests made with the Knoop or Vickers indentors under test loads in the range from 1 to 200 gf. This is an excerpt from Standard Test Methods for Metal Powders and Powder Metallurgy Products, 2016 Edition, with ISBN(s): 9781943694037.
