AbstractThe objective of this lab is to understanding of the study the effect of cold rolling onthe strength of aluminum. Study the effect of cold rolling on the strength of thealuminum Strips. To perform this experiment two strips were annealed and the othertwo were not annealed.IntroductionCold rolling is a process by which the sheet metal or strip stock is introduced betweenrollers and then compressed and squeezed. The amount of strain introduceddetermines the hardness and other material properties of the finished product.ProcedureMATERIALS:4 Aluminum strips 20” long, 0.06” thick, and about 0.7” wideGreaseEQUIPMENT:Metal Work Bench - Rolling MillFurnaceTinius Olsen Tensile Testing MachinePliersVernier calipersRulerTensile Specimen CutterFilePROCEDURE:1.Strips A and C will not be annealed; strips B and D will be annealed.2.Anneal both the 6.5” strips and the 13.5” strips for the coupons B and D in theoven for ½ hour at 650F before use. Mark and set aside the 6.5” coupons A0, B0,C0, and D0.3.Adjust the rollers to reduce the thickness close to 0.054” and roll strip A.4.Repeat above procedure for strip B.
