The Vickers hardness test is a very reliable method for measuring the physical properties of materials. It is a very popular method in engineering, industrial use, and the oil and gas industries. The Vickers hardness test allows engineers to inspect materials before they undergo production or post-production processes such as heat .
A number of factors influence hardness tests results. As a general rule, the lower the load you use in the hardness test, the more factors that need to be controlled to ensure an accurate conclusion of the hardness test. Here are a few of the most important factors to consider to ensure an accurate conclusion from a hardness test. CONCLUSION AND RECOMMENDATION From the experiment, the hardness testing is to measure of hardness of material’s resistance to localized plastic deformation. This experiment also experienced students to be able to perform the hardness using two type of machine with specific of hardness testing but in this experiment we just used the Rockwell .
Hardness testing can be applied to various types of materials, some of which are listed below: Metals and alloys. Ceramics. Elastomers. Polymers and plastics. Films. Rocks and minerals.
