Analysis Of Compression Creep Deformation Of 7050 Aluminum Large Scale Open Die Forgings During The Solution Heat Treatment Process, Ashley Lopez, Elysha Cole
Materials Engineering
A stress, ranging from 104.17 to 166.67 psi, was applied to 0.5 in diameter cylindrical samples of 7050 aluminum using a manufactured fixture that applies stress using an indenter with a diameter of 0.127 in. The stress range used replicates the stresses produced on large scale forgings weighing up to 4000 lbs. We chose a maximum, medium and low stress as our stress parameters. The samples were placed into the fixture for stability then placed in a furnace heated to 890°F which is the solution heat treatment temperature for 7050 aluminum. The heat treatment times varied between 4 and 24 …

This report details the process of designing and producing a manifold that connects ultra-high purity (UHP) pressure and vacuum switches to an air supply so that the parts may be tested in an environmental chamber. Using the DMAIC (define, measure, analyze, improve, and control) methodology of problem solving, progress on the project includes thorough research about the problem, preliminary design solutions, iterative prototyping, and testing specific functionalities. Manufacturing engineering topics of tooling, fixturing, metrology, quality, and machining with manual and computer numerical control (CNC) varieties of both mills and lathes are applied during the course of the project. The report …
