Description: The Vickers hardness test is a measure of a material's resistance to permanent deformation at the surface using a diamond indenter. Although not strictly speaking a property, hardness is often used in materials selection process. The equation relates specifically to the Vickers testing process and equipment.

TeX format: HV = \frac{2sin(68\degree )F}{d^2}

HV {HV} = Vickers Hardness number (Pa) {Pa}
F {F} = Indenter load (N) {N}
d {d} = Mean indent diameter (m) {m}

Keywords: hardness • Vickers • diamond indent • testing • surface • yield strength
