Abstract
A method for producing an energistic porous warhead casing comprises the steps of mixing aluminum and magnesium powders in an Al:Mg weight ratio from about 22:78 to about 28:72, isostatically pressing said powders to form a preform of appropriate shape and with a density from about 20 to about 40 percent of the theoretical density, and heating said preform in an inert atmosphere at a temperature from 350 C to about 425 C until the density reaches 60 to 70 percent of the theoretical density.
