Feasibility of Investment Casting Preforms for Phalanx Penetrators.
Abstract
The objective of this program was to demonstrate, in a preliminary fashion, that depleted uranium 2 w/o molybdenum alloy Phalanx penetrators can be produced by the investment casting process and to provide cast penetrators for ballistic evaluation. Results of the work have shown that sound penetrators, free of internal voids, can be produced by investment casting. As-cast penetrators and penetrators heat treated to the specification hardness (28-32 Rc) have ductility equal to, or superior to, that of wrought penetrators. Under the melting and casting conditions used in this work, an increase in carbon content beyond specification limits occurred in sequential melts using approximately 50 w/o recycle material. It is believed that this problem can be solved by adjusting melting conditions.
