3.1 Macro Hardness Test Methods 3.1.1 Rockwell Hardness Test The Rockwell hardness test method consists of indenting the test material with a diamond cone or hardened steel ball indenter. The indenter is forced into the test material under a preliminary minor load 𝐹0 (Fig. 1A) usually 10 kgf. When equilibrium has been reached, anPDF | On Mar 26, 2015, Md Raziun Bin Mamtaz published Microstructure Examination and Hardness Test | Find, read and cite all the research you need on ResearchGateT able 2. Steel samples with their hardness in rockwell B and C scale. From the above hardness table it can be seen that all 10 sample hardness can not be measured with the same rockwell scale. So for comparison and plotting, all hardness value is converted to Rockwell B scale[2]. Converted value of hardness to the Rockwell B scale has been3.2 Conducting the Test. Positioning the Sample: Secure the material sample in the testing machine.; Selecting the Indenter: Choose the appropriate ball diameter based on the material hardness.; Applying the Load: Gradually apply the specified load using the machine.The load should be maintained for a predetermined dwell time, usually between 10 to 15 seconds.
4) For Rockwell hardness testing, no optical measurements are required; all readings are direct. There are two common methods applied to measure material hardness macroscopically: Rockwell and Brinell. Rockwell hardness differs from Brinell hardness testing in that the indentation size is measured in Brinell The Brinell hardness test ing uses indenters made of st eel to test materials with hardness values of up to 350 HB, or of hard metal (tungsten) to test materials with har dness values from 350 to .
