Design and fabrication of work holding device for a drilling machine.
. P load on the indenting tool kg D diameter of steel ball mm d measure diameter at the rim of the impression mm It is desirable that the test load are limited to a impression diameter in the range of 25 to 475 mm. Approximate loads and Brinell Hardness Numbers. Due to different indenters loads and load durations there are a variety of indentation hardness mainly Brinell hardness Rockwell hardness Vickers hardness and micro-hardness.
By Raphael Silva Augusto. Rate of loading temperature notch effect affect toughness. The Vickers and Brinell hardness scales correlate well over a wide range however with Brinell only producing overestimated values at high loads.
Rockwell hardness test Brinell hardness test Vickers hardness test Knoop hardness test Shore hardness test Mohs hardness test are tests that measure the hardness. This is affected by the strength and plasticity of the material. BHN Brinell Hardness Number.

TESTING THE HARDNESS OF METALS MECHANICAL PROPERTIES OF METAL. The Vickers hardness measurement range is large and it can measure materials with a hardness in the range of 10 1000HV and the indentation is small.
