WebMacroindentation tests There are various differently used macroindentation tests. The most frequently used include the Brinell hardness test, the Rockwell hardness test, and the Vickers hardness test . The Brinell hardness test involves pressing a steel sphere against the material surface for a given while, usually 10–15 seconds. In a traditional indentation test (macro or micro indentation), a hard tip whose mechanical properties are known (frequently made of a very hard material like diamond) is pressed into a sample whose properties are unknown. The load placed on the indenter tip is increased as the tip penetrates further into the specimen and soon reaches a user-defined value. At this point, the load may …
