Brinell hardness test was used in attempt to examine the relation of the .Specimens of various metals (aluminium, brass, copper, high speed steel in this experiment) Indenters Rockwell hardness testing machine (b)Theory There are many de nitions for hardness depending on the material. For metals, the most appropriate one would be ‘resistance to permanent deformation’. Hardness can be Hardness Testing and Specimen Preparation Hardness testing is a useful tool for the evaluation of materials, quality control of manufacturing processes and in research and development work. It gives an indi-cation of a material’s properties, such as strength, ductility and wear resistance. In this application note we will consider
This document describes procedures for harness testing of metallic materials using the Rockwell scale. The Rockwell hardness test measures the indentation made by specific loads on a material's surface. There are different Rockwell scales that use varying loads and indenters depending on the material. The experiment uses a Rockwell hardness tester with a diamond . The paper presents a comparison of three strain measurement methods. The mechanical parameters of S355 grade steel (yield strength, tensile strength, modulus of elasticity) were determined in .
The laboratory report is about two experiments: Microstructure examination and Hardness test. In hardness test three different specimens of high speed steel, mild steel and Aluminum was examined for• Rockwell hardness testing is used to test hardness in the macro range test force within 49.03 newton (5kg) to 1471 newton (150kg). • It is a differential-depth method which used the residual depth of indentation left by the indenter is measure to determine the hardness value of .- The test sample should be clean, dry, smooth and oxide-free surface . to students in the class lab by the Qness hardness test machine in Fig. 4.

REPORT In your laboratory reports must have the followings; a) Cover b) A short introduction c) All the necessary calculations using measured data.The Hardness Testing of Metals laboratory was conducted using the Rockwell B Hardiness Test and Brinell Hardness Test. Both tests were performed to test the strength of the following materials: aluminum, brass, and steel. . and the metal removed. You must report any deviations from expected procedures or equipment performance. Hardness of .
The Brinell hardness test is used for hardness testing larger samples in materials with a coarse or inhomogeneous grain structure. The Brinell hardness test (HBW) indentation leaves a relatively large impression, using a tungsten carbide ball. The size of the indent is read optically. Used for materials with a coarse or inhomogeneous grain .
Result and Analysis The points used for the hardness test was as shown in the diagram below: Figure 3: Diagram of the specimens and its designed points. Table 4: Diameter and Vickers Hardness Test Value of the specimen Point .Hardness Test 2/5 the microscope is in millimeters. The larger diameter indentation corresponds to a softer material and lower Brinell number. VICKERS HARDNESS TEST The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees
7. SPECIFICATION OF HARDNESS TESTING MACHINE AND INDENTERS A hardness test can be conducted on Brinell hardness testing machine, Rockwell hardness machine or Vicker hardness testing machine. The specimen may be a cylinder, cube, thick or thin metallic sheet. A Rockwell hardness testing machine along with the specimen is shown in Figure 2.VICKERS HARDNESS TEST: The Vickers hardness test uses a square base diamond pyramid as the indenter. The included angle between the opposite faces of the pyramid is l36°. The Vickers hardness tester operates on the same basic principle as the Brinell tester, the numbers being expressed in the terms of load and area of the impression.
The advantages of the Vickers hardness test is the extremely accurate readings can be taken and just one type of indenter is used for all types of metals. The Vickers test is capable of testing soft and hard material. The disadvantage of this method is it takes time because the indentation must be measured under the microscope. Besides, the sample must .
