The E-357 Aluminum Statistical Properties Project has received funding as part of the CIR program. The E-357 project will produce cast A&B design property allowables for this aluminum alloy for inclusion in the MMPDS (old Mil Spec Handbook 5) to meet FAA requirements. This will allow aerospace design engineers to specify castings without using design safety factors. Various working groups are actively looking at melt practices, test casting gating and filling, heat treatment parameters, testing protocol, and weld repair standards. The initial casting trials were conducted for the 1.5 x 2.5 inch plate cast in both horizontal and vertical gating approaches, also a heat treat study at various participating foundries. These plates have been tested for tensile properties and microstructural evaluation. A presentation was made on project status and the other AMC projects to the JDMTP (Joint Defense Manufacturing Technology Program) Metal Sub-panel during the AMC Annual Project Review at the Sheraton O’Hare Gateway Suites, June 25-26, 2008. The initial project results were reviewed at the general meeting of the project working group held at AFS October 8, 2008 and also at the MMPDS Fall 2008 meeting in Orlando. Work is now continuing to optimize the gating systems and conduct a heat treat study.
