WebJun 16, 2024 · The diamond indenter is in the shape of a four-sided pyramid. After touching the part, the machine soon reaches the pre-determined force value. It stays at the same load for a certain time. Then, the measuring of the indentation takes place. Calculating the Vickers hardness value uses the following formula: Webindenter is 0. 75. If tangents are drawn to the ball at the impression edges for d/d = 0. 75, they meet below the center of the impression at an angle of 6°, the angle chosen for the Vick-ers indenter. use of diamond allowed the Vickers test to be used to evaluate any material (except diamond) and, furthermore, had the very important advantage WebAitawade Industries.
