Unformatted text preview: 1 MSE 250 LAB #6 Cold Working Introduction This laboratory exercise is introduce you to the effect of cold work on FCC alloys, 70-30 Brass and 2024 Aluminum. In addition, you will measure the hardness at different levels of cold work. Each team will appoint a leader and that person will be responsible for organizing the collection of data for their team. Experimental Procedure Each team will be given five specimens. These specimens are to be cold-rolled, resulting in the specified %CW (10%, 20%, 30%, 40% or 50%). One simple way to estimate %CW is based on the thickness reduction. For example, it the initial specimen is 0.125 inch, for 10% CW the thickness should be around 0.112 inch. However, the correct %CW should be based on cross- sectional area, therefore it is necessary for you to measure the width as well as after the cold rolling to obtain the correct %. Cold work is done by passing the specimen through a set of rollers, reducing the specimen in thickness. Depending upon temperature used during deformation, it is known as either hot or thickness....
