Brinell-Hardness data (HBW 2.5/62.5) of aluminum alloy EN AW-2618A after different aging times and temperatures [PDF]
The article covers data on the Brinell hardness of the forged precipitation-hardened aluminum alloy EN AW-2618A in the initial T61 condition (i. e. slightly underaged) and after isothermal aging for up to 25,000 h at aging temperatures between 160 °C and

An analytical model of Brinell hardness for power-law hardening materials
In the Brinell hardness test a hard spherical indenter is pressed into a metallic material. Due to the inhomogeneous distribution of stresses and strains the hardness measure is not a unique function of the material properties alone, but also depends on ...

Proposed definition for the Brinell hardness indentation edge [PDF]
The industrial Brinell hardness test has been in common use for over 100 years. The test is defined by standardized procedures stating that the Brinell hardness value is proportional to the test force divided by the surface area of the indentation. The test procedures require that the surface area be determined by measuring the indentation diameter ...
