Porous fiber sintered metal consists of sintered short metal fibers that produce chattering. The metal is widely used in audio and domestic electrification, and in such mechanical parts as bearings, filters, and vibration suppressors. It is difficult, however, to calculate the hardness of porous fiber sintered metals from dent dimensions because they are characteristically viscoelastic. In the present paper, carbon steels are tested and the relationship between the porosity ratio and the depth of indentations are clarified in experiments.<br>The shapes of indentations are observed and analyzed in scanning electron microscopy, indicating the following:<br>1) The hardness value, depth of an indentation caused by indenter pressure, and elastic recovery are all related to the metal porosity ratio.<br>2) The depth of indentations increases with incremented porosity ratio.<br>3) The Rockwell superficial hardness value is negative.
