Rebar

Rebar Purpose: The purpose of the different types of rebar experiments was to show how processes such as annealing, rolled, hardened, will affect the grain structure, of a sample of normalized rebar. All the rebar samples were prepared from the different processes such as annealed rebar, normalized rebar, hardened rebar, rolled rebar. The samples were then placed in a thermoplastic machine, each was sanded and polished and etched to examine the grain structure of each sample of rebar .The final experiment Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES) was done by taking steel shaving and dissolving them and diluting them in a known solution. Then the solution is then analyzed for its atomic makeup to find the types of elements that go into making steel. The results of the experiment will be shown in a report. Procedure: A. Steel Grain Analysis on Mounted Samples 1. The normalized rebar sample was cut using the Samplemet 2 Abrasion cutter about 1/2 inch from the sample given by the lab instructor. The rebar was placed securely in the vice to prevent the rebar from coming out of the vice. The sample was then cut by lowering the handle slowly sample, rebar, solution, machine, normalized, grain, each, steel, samples, different, annealed, water, structure, rolled, puck, pearlite, hardened, ferrite, experiment, shavings, rockwell, icp, beaker, after, acid, using, under, three, sure, rinsed, put, polishing, polished, placed
