TITLE Hardness Tests And Charpy Impact Test OBJECTIVE 1. To compare the hardness of the carbon steel‚ mild steel and ASSAB steel using three different hardness tests‚ which are Vickers Hardness Test‚ Rockwell Hardness Test and Brinell Hardness Test. 2. To study the hardness of mild steel‚ carbon steel and ASSAB which is an important in engineering to design structures or components that related in mechanical properties 3. To determine the resistance of carbon steel and mild steel

study the hardness of different types of materials‚ and to understand the significance of this property in materials. The materials and the aforesaid property have significant use in civil engineering. Hardness is defined as a measure of a material’s resistance to localised plastic deformation (i.e. small dents or scratches). As said above‚ a variety of metal alloys were used in the experiments to understand how each of these metals is characterised as a hard metal and to compare the hardness of different

MATERIAL SCIENCE EXPERIMENT-2 NAME OF THE TEST: HARDNESS TEST AIM : OBJECT TO DETERMINE HARDNESS TEST OF A METARIAL INTRODUCTION It become necessary to test engineering materials before they are accepted for processing‚ buying or applying to determine whatever or not they meet the spefications required. One of the tests is hardness test. The Rockwell and brinell machines are those most commonly used for this purpose. PROCUDURE AND LABORATORY REPORT 1. Understad

explain what the Rockwell hardening test is and why it is used‚ how the experiment was conducted‚ data that was found‚ and the importance of testing the hardness of materials. This experiment explains and proves how the hardness of materials can be increased by alloying and heat treating. Intro – Rockwell Hardness Testing Soft and hard qualities exist in materials. In materials‚ hardness measures the ability of a material to resist scratching‚ indentation‚ or penetration. Hardness cannot be expressed
