Vickers hardness test - Wikipedia

The Vickers hardness test was developed in 1921 by Robert L. Smith and George E. Sandland at Vickers Ltd as an alternative to the Brinell method to measure the hardness of materials. The Vickers test is often easier to use than other hardness tests since the required calculations are independent of the size of the indenter, and the indenter can be used for all materials irrespective of hardness.Ores of manganese with hardness - Henan,Comparison of Ore Hardness Measurements for Grindi. 201356Comparison of Ore Hardness Measurements for Grinding Mill Design for the Tenke Project John Starkey1, Principal Consulting Engineer ore hardness measurements pare with each other when done on the same samples Values for A x b are all close to or above 100 and this corresponds to ores that are moderatelyComparison of instrumented Knoop and Vickers,Comparison of instrumented Knoop and Vickers hardness measurements on various soft materials and hard ceramics .
