BMM1511 Engineering Mechanics Lab 1 Lab E1 Vickers Hardness Test Section/Group Section 02 GroupThe formula applied to find the Rockwell hardness (HR) are: Regular Rockwell hardness: hH R =100− (For Brale indenter) 0.002 h H R =130− (For Steel Ball indenter) 0.002 Superficial Rockwell Hardness: H R =100− h (For Brale Indenter) 0.001 h H R =130− (For Steel ball indenter) 0.001 Where h is the incremental depth.Hardness is a property of a material to resist being indented. The Rockwell hardness test measures the depth of an indentation produced by an indenter due to the force/load applied. The hardness of a material is measured by the material’s ability to resist indentation. Therefore, a harder material will have a higher Rockwell hardness number.
