Vickers Hardness Testing Machine Diagram

The microhardness test procedure astm e 384 specifies a range of light loads using a diamond indenter to make an indentation.

Vickers hardness testing machine diagram. The vickers test has two distinct force ranges micro 10g to 1000g and macro 1kg to 100kg to cover all testing requirements. The vickers hardness test can help with the material selection process for your chosen application. Hardness testing machine vickers limited engineering group container packaging machinery division vickers armstrongs crayford works telephone. The angle was chosen so that the vickers hardness values are comparable to a certain degree with the brinell hardness values applies to approx.

The plunger pi see arrangement diagram in h. Catalogue may be sluggish and if so the bearing should. It s easy to use with advantages over other tests that include less risk of damaging your test piece. For the vickers hardness test a square base pyramid with a opening angle of 136 is used as the indenter opening angle angle between two opposite surfaces of the pyramid.

The vickers hardness test was developed in 1921 by robert l. 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. The vickers hardness test method also referred to as a microhardness test method is mostly used for small parts thin sections or case depth work.
