Can a microhardness tester HMV measure the hardness of high temperature materials?
Microhardness testers (HMV) usually cannot directly measure the hardness of high-temperature materials. Conventional microhardness testers perform tests under room temperature environments; high temperatures will cause changes in the structure and properties of the material, and will also cause damage to components such as the indenter and loading system of the hardness tester, affecting the precision and service life of the equipment.
However, for situations where it is necessary to understand the hardness performance of materials in a high-temperature state, indirect methods can be adopted. For example, first cool the high-temperature material to room temperature, then measure its hardness, and then combine the high-temperature performance data and relevant theoretical models of the material to estimate the hardness of the material at high temperatures. In addition, there are also some specially designed hardness testers that can perform tests within a certain high-temperature range, but such equipment is usually complex in structure and high in cost.
