Witryna14 mar 2024 · It is necessary to note that microhardness testing and instrumented indentation differ in that the area of contact is not measured as such but calculated from the indentation depth. The area function was A=24.355h_c^2+165.6h_c, the first coefficient being found with the use of a laser goniometer to measure the diamond … 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 formed; these tests can be performed on a macroscopic or microscopic scale. When testing metals, indentation hardness correlates roughly linearly with tensile strength, but it is an imperfect correlation often limited to small ranges of strength and hardness for each indentat…
