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

width of the specimen. The tests were performed at a 2 mm/min. The samples were connected to the clamps of the machine from the both sides. Afterwards‚ the tensile forces were applied from the ends and the overload failure mode was examined. Furthermore‚ the test results were measured as the area under the load-displacement curve up to the peak load. The failure mode was determined from the failed samples. 2.3 Metallography The macroscopic examination also termed as macro test were used to assess the

Hardness Tests and Charpy Impact Test Objectives: 1) To compare the hardness between mild steel‚ carbon steel through Vickers Hardness Test. 2) To compare the hardness between High Quality Carbon Steel and ASSAB steel through Rockwell Hardness Test. 3) To compare the hardness between carbon steel and mild steel through Brinell Hardness Test. 4) To study the differences between mild steel and carbon steel upon Charpy Impact Test. Introduction: Hardness is a measure of the resistance

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

FLAME TEST Summary The purpose of this lab was to see how different compounds can change color while in a flame and with this color‚ I can identify the compound. The test involve putting sample element and see what color appears. Also Thermal excited electron goes from low to high energy level which raises the color but when the excitation ends electron gets to lower level which makes the color back to normal. In order to determine the identity of several unknowns‚ I will perform flame tests and

Boake‚ Hannah Harper Various Color of Light as the Effect of Electron Emission Objective Observe the characteristic colors produced by certain metallic ions when vaporized in a flame. Identify the unknown metallic ions by means of its flame tests. Background When atoms absorb energy‚ electrons move into higher energy levels‚ and these electrons lose energy by emitting light when they return to lower energy levels. Energy levels are fixed energies that electrons can have. Ordinary light

Flame Tests By: Jordan Anthony‚ Zack Balog‚ and Evan Degraw Regents Chemistry class‚ Union Springs High School‚ 4th period January 19/2015 The purpose of this lab was to see what colors are characteristic of particular metallic ions in a flame test and use their characteristic color to identify other elements. Another purpose is to understand how fireworks work. This experiment will help one understand how a flame test is performed and that every metal has a unique bright

Our flame test was in lab class‚ where the main aim was to tested different solid metals in the flame in order to observe the wide variety of colors those chemicals also sometimes compounds (by mixing them) they produced‚ the second one was to identify unknown metals based

Citrate Test: Some bacteria can use citrate as a source of carbon. To test if the unknown bacteria uses citrate as a source of carbon‚ Simmon’s citrate agar was used as the medium on which the bacteria was grown. The Simmon’s citrate agar consists of sodium citrate as the source of carbon‚ ammonium dihydrogen phosphate as the source of nitrogen along with pH indicator such as bromothymol blue. Procedure: The Citratase activity was detected by inoculating the unknown bacteria on the slant surface
