OBJECTIVE The objective of this lab is to measure the impact strength at different temperatures for steel and aluminum, determine the Ductile to Brittle Transition Temperature of the alloys, if any. And to determine if temperature has any effect on the strength of the materials tested. MATERIALS & EQUIPMENT 10 Samples of each(measuring .375”x.375”x1” and making sure they are notched on one side) -1018 steel(18% carbon, 82% pure iron) -Aluminum Alloy( Al+ 0.5% Mg2Si) Hot Plate Water(for boiling) Dry Ice & Acetone Ice Water Boiling Liquid Nitrogen Tongs Charpy impact machine PROCEDURE Put two samples of Aluminum Alloy and 1018 steel into each of the following: a pot of boiling water (100 degrees Celsius), let two of each sample sit out in the open air (25 degrees Celsius), two samples of each in an ice water bath (0 degrees Celsius), two samples of each in dry ice and acetone (-78.5 degrees Celsius), and two samples of each in Boiling liquid nitrogen (-195.6 degrees Celsius). Allow the samples to reach the

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
