Feasibility of Squeeze Casting the Base for the PATRIOT Warhead XM248E1.

Abstract

Squeeze casting is a hybrid of permanent mold casting and forging techniques. In this metalworking process molten metal is metered into a die cavity and pressure is applied to the solidifying metal. Suitable use of the optimized process parameters can eliminate common casting defects such as shrinkage and gas porosity and can lead to improved mechanical properties over those of sand or permanent mold castings. This program was aimed at squeeze casting the base for the PATRIOT warhead XM248E1 from a wrought aluminum alloy (6061 AL). The possible enhancement of properties resulting from the use of this alloy, as well as from the squeeze casting process itself, and the potential for cost reduction were two areas of major interest. This final report describes the equipment and the squeeze casting tooling, procedural details, and the evaluation of the castings, and is a summary of IITRI's results in squeeze casting the PATRIOT warhead base.
