Hardness tester (indentation tester)
Last Updated December 27, 2018
Introduction of hardness testing machine (indentation tester)
Overview
Principles
The conventional Vickers hardness test method observes the size of the hollow that forms the specimen surface after pressing indensed is observed with an optical microscope equipped with the test machine, and the hardness value is determined from the diagonal length of the hollow. However, unlike the conventional Vickers hardness tester, the tester is equipped with a displacement meter in the indenator drive part, and it is designed to show the material characteristics by measuring the applied test force and the indensity of the indenter.
Characteristics
The test force and push depth to be loaded during the indentation process can be continuously measured and displayed as a graph. From this graph, you can find plasticity, elasticity, and creep deformation, as well as intensive factors that are associated with the Young's density of the material.
Points to note
During the hardness test, cutting may be required to place the sample on the specimen table.
