Experiment on Vickers hardness test. Group 10 Samuel Olakanmi (202202443) Atlarelang Mhateng (202206923) Golebaone Motsumi (202206035) Katlo Morwamang(20200402) Ame Seamolo(202304327) Abstract Mechanical hardness testing is important in the evaluation of properties of metallic materials. Determining the hardness of aFor most hardness testing, 50 kg is maximum. The Vickers test can be used for all metals and is one of the widely used test among hardness tests. The unit of hardness is known as the VICKERS PYRAMID NUMBER (HV) or DIAMOND PYRAMID HARDNESS (DPH). The hardness number can be calculated by the load over the surface area of the indentation .Conclusion: The hardness test experiment was done using a Brinell and a Rockwell Testers. The data obtained was recorded and compared. The experimental and referenced values for each metal were compared. Table 2 showed that the percent differences for Rockwell Test were smaller than for the Brinell test. This concludes that the Rockwell test is .
15.2.3.2 Hardness Test.

The Vickers hardness test can be a micro indentation test and also for the macro hardness test. It is mainly divided into two steps. The test force (load) F is applied on the specified square base pyramid shaped diamond indenter for the specific time when it collides with the testing sample object in the direction normal to the test surface.3.2 Conducting the Test. Positioning the Sample: Secure the material sample in the testing machine.; Selecting the Indenter: Choose the appropriate ball diameter based on the material hardness.; Applying the Load: Gradually apply the specified load using the machine.The load should be maintained for a predetermined dwell time, usually between 10 to 15 seconds.Brinell test in Sweden in 1900. The oldes t of the hardness test methods in common use today, the Brinell test is frequently used to determine the hardness of forgings and castings that have a grain structure too course for Rockwell or Vickers testing (http ://www.instron.co.uk ). 2.2. Case hardening improves both the wear
Vickers hardness testing also is known as the Diamond pyramid hardness test. Because we use the Diamond pyramid as the indenter. The same testing machine which is used for the Brinell hardness testing machine can be used for the Vicker’s hardness test also.; Unlike Brinell hardness testing, we do not need to change the indenter for the different materials. we .
