WebAug 26, 2024 · Macrohardness tests are the most widely used methods for rapid routine hardness measurements. It is the type of hardness testing used for normal-sized … The term "macroindentation" is applied to tests with a larger test load, such as 1 kgf or more. There are various macroindentation tests, including: Vickers hardness test (HV), which has one of the widest scales. Widely used to test hardness of all kinds of metal materials (steel, nonferrous metals, tinsel, … See more Indentation hardness tests are used in mechanical engineering to determine the hardness of a material to deformation. Several such tests exist, wherein the examined material is indented until an impression is … See more The term "microhardness" has been widely employed in the literature to describe the hardness testing of materials with low applied loads. A more precise term is "microindentation … See more When hardness, $${\displaystyle H}$$, is defined as the mean contact pressure (load/ projected contact area), the yield stress, $${\displaystyle \sigma _{y}}$$, of many materials is … See more Different techniques are used to quantify material characteristics at smaller scales.
