How a Vickers Hardness Tester Works
Diamond Pyramid Indentation Principle
A diamond-shaped indenter is pressed into the material surface under a controlled load.
Test Load Application Process
A specific force is applied for a fixed duration to create an indentation.
Hardness Calculation Method (HV)
Hardness is calculated based on the diagonal length of the indentation.
