Micro vickers hardness calculation
WebThe Vickers Hardness number (HV) is the ratio of the load applied to the surface area of the indention. This is done with the following calculator and formula. HV = P / ( 0.5393 d 2 ) or HV = 0.1891 F / d 2 Where: P = Force (kg) d = Area of indentation (mm) F = Force (N) 1 kgf = 9.80665 N Web24 mei 2024 · Hardness is a measure of how well a solid material resists permanent shape change when a compressive force is applied. …
