A test to determine the hardness of metals and alloys by hydraulically pressing a steel ball into the metal and measuring the resulting indentation.
- In heat treating, one determines the hardness of pieces of metal by the Brinell hardness test.
- Optical microscopy, scanning electron microscopy, and Brinell hardness tests were carried out.
- The machine permits highly accurate Brinell hardness tests to be carried out on parts with different dimensions.
Named for Johan August Brinell (1849–1925), Swedish engineer.
