Methods
1. Experimental Overview
Using hardness tester, we make indentation on the surface of the specimen. Then measure diameter of indentation with microscope.
2. About Hardness tester
Figure 1. Schematic of Hardness Tester
Figure 1 shows structure and name of each part of Hardness tester. Anvil is where the specimen is located. When we lean back operating lever, load is applied to the specimen. If we rotate handwheel clockwise, anvil will move upward. Dial gauge shows indented depth. Actually, however, during Brinell hardness test the dial is just for reference.
3. Procedure
1) Place the specimen on the disk
2) Turn the handle clockwise until the specimen touch with upper side indentor
3) To make the scale point zero(12 o'clock), turn more carefully. It's preset for test under same condition.
4) Push back the lever of right side to apply the load on the specimen(187.5kgf)
5) Wait a moment about 3~5s
6) Remove the load by pulling the lever again
