1. What is Brinell hardness tester?
The Brinell hardness tester uses the oldest method of hardness testing commonly used today. It was invented in Sweden by Dr. Johan August Brinell in 1900. This test is often used to determine the hardness of castings and forgings whose grain structure is too course for accurate Rockwell or Vickers testing.
2. What do you perform a Brinell hardness test?
Brinell Hardness Test Procedure
In this test method, a predetermined force (F) is applied to a tungsten carbide ball of fixed diameter (D) and held for a predetermined time period, and then removed. The spherical indenter creates an impression (permanent deformation) on the test metal piece.
3. How does a hardness tester work?
A hardness test is typically performed by pressing a specifically dimensioned and loaded object (indenter) into the surface of the material you are testing. The hardness is determined by measuring the depth of indenter penetration or by measuring the size of the impression left by an indenter.
4. How do you read a Brinell microscope?
Manual reading is easy and straightforward. You look through the lenses, focus the optics, position in the lens on the impression and read the result in mm. The result in mm is then converted to HBW (Hardness Brinell) by looking up the mm measurement and the table provides the hardness.
5. What is the difference between Brinell and Rockwell hardness test?
The Brinell hardness testing uses a 10mm hardened steel ball, while the Rockwell test uses either a much smaller steel ball (<4mm) or a diamond cone, depending on the material being tested. The Rockwell test measure the depth of the indentation, while the Brinell test measures the width of the indentation.
6. What indenter is used for Brinell test?
spherical indenter
In the Brinell hardness test, an optical method, the size of indentation left by the indenter is measured. In contrast to the likewise optical Vickers method,which involves a pyramid-shaped indenter being pressed into a specimen, the Brinell method uses a spherical indenter.
7. How do you find the Brinell hardness number?
The Brinell hardness number (BHN) is calculated by dividing the load applied by the surface area of the indentation. Figs. 6.72–6.74 show some of the Brinell hardness test sites.
8. Is standard for Brinell hardness testing?
ISO 6506-1:2014 specifies the method for the Brinell hardness test for metallic materials. It is applicable to both fixed location and portable hardness testing machines.
9. What is a Brinell microscope?
This instrument is a low-power hand-held microscope for measuring the diameter of a Brinell hardness indentation. The Brinell hardness value is calculated from the indentation diameter measurement, ball diameter and applied force. The Brinell hardness test was developed around 1900 for testing the hardness of metals.
