Brinell hardness test was used in attempt to examine the relation of the .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
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 considerSpecimens 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- 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. Different materials specimens will be . REPORT In your laboratory reports must have the followings; a) Cover b) A short introduction c) All the necessary calculations using measured data.
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 forEach hardness test method, or scale, is defined with a particular type of indenter, a specified . indenter. To carry on the test, the diamond indenter is pressed on to a prepared metal surface to cause . the indenter on the specimen for 10 to 15 s. (in this lab we will be using 15 seconds).The Vickers hardness test is ideal for testing of all metals and is therefore the method with the widest range of application. The hardness test method according to Vickers is described in standards ISO 6507 (Metallic materials – Vickers hardness test – Part 1: Test method) and ASTM E384 (Standard Test Method for Microindentation Hardness (1gf - 200 gf) of Materials .
