What is the Brinell test?
BRINELL TEST is a test used to determine the hardness of materials. Metals are commonly tested in this way and the Brinell test can also be used in forests and some other materials. This is a form of testing of materials in which the aim is to learn more about the material by submitting the sample a set of standardized tests. BRINELL test results for a number of common materials, from mahogany to carbon steel, are easily accessible. In the Brinell hardness test, the solid metal ball is pushed into the material sample with the set amount of weight acting as a pressure on the ball. The ball is held in place for 15-30 seconds and then the weight is released. The ball leaves the plant and the hardness can be determined by distributing the weight of the indentation areas. Testers want to avoid uses that are so large that it disrupts the test results. The materials that are designed from this also differ, depending on the material tested again. Chrome steel is one choice, just like tungsten carbide. After publishing the results of teStu can be published in size and composition of the ball so that people have a reference framework.
To understand why balls of different materials and sizes are used, instead of a standardized ball, think about pushing your hand with a cake. With minimal pressure, the hand should quickly travel from the top of the cake to the cake plate. Now think about using the same amount of pressure, with the same hand on the marble kitchen counter. The counter would probably be immobile, and if the pressure increases, the hand would probably break before the offset appears on the counter. This example illustrates why different materialbrinell tests are used, with the size and composition of the ball depends on what is tested.
Many people use machines that have been specially designed to administer the Brinell test when they perform this material test. The machine includes measuring devices that can very precisely determine the diameter of the indentation. Is alsoIt is possible to use a system modified for the Brinell test if the pressure weight can be controlled and a microscope is available for indentation measurement.
