Problem Statement Normalizing is a heat treatment process usedto relieve internal stresses, refine the grain size and improvemechanical properties. Normalizing is done to give steel a uniformand fine-grained structure. Normalizing is often used for ferrousalloys that have been austenitized and then cooled in open air.Normalizing not only produces pearlite, but also bainite andsometimes martensite, which gives harder and stronger steel, butwith less ductility than full annealing. The normalizing experimentin Materials Science lab is conducted by preparing a small sampleof metal. The metal will be heated inside a small furnace up to acertain temperature and it is expected that upon heating the metalwill have a uniform temperature thoughout the body. The hot metalis then cooled until its temperature is back to room temperatureagain. You will help to establish the normalizing experiment in bydesigning all necessary requirement, such as the following: -Decide the material type and size. - Decide the heating temperatureand the heating time. - Determine the cooling time, i.e. up to roomtemperature. - Generate the heating and cooling charts, i.e (timevs temperature for each heating and cooling process). For thereport, you have to show the assumptions taken, the properties ofmaterial, details of calculation, and other necessary engineeringaspects.
