Casting Solutions for Readiness Metallic Materials Properties Development and Standardization (MMPDS) Cast High-Integrity Alloy Mechanical Property Standards (CHAMPS)
Abstract
The Cast High-Integrity Alloy Mechanical Property Standards (CHAMPS) Statistical Properties Project goal is incorporation of material property design data for additional cast alloys, A206 high strength aluminum for sand casting in the initial phase and then 15-5PH and 17-4PH stainless steels for investment casting in the second phase, into the Metallic Materials Properties Development and Standardization (MMPDS) handbook, which replaced Mil-handbook 5, so that this material can be specified and used to design and manufacture flight critical components in military and civilian aircraft. This builds on the original American Metalcasting Consortium (AMC) E357 effort of establishing a framework to design a series of test specimens that encompass the various section thicknesses used in these applications utilizing process simulation software, validating the approach metallographically, coordinating the collection of required samples from a consortium of qualified foundries, and submitting the data for statistical analysis and approval by the MMPDS board for incorporation into the MMPDS standards. The benefit to the Defense Logistics Agency (DLA) is the development of statistical-based property data to permit the use of castings across a broader range of applications and will allow the Engineering Support Activities (ESA) at the DLA to make cast alloy conversion / replacement decisions with assurance using statistical data on tensile, compressive, shear, and bearing properties from the Federal Aviation Authority (FAA) recognized source, the MMPDS Handbook. This will also reduce lead times with cast components competing on an equal basis with forging and assemblies from sheet, plate, and extruded mill products.
