Abstract: A method of making aluminum nitride armor bodies is provided. The method starts with low cost bulk raw material, in the form of aluminum or aluminum alloy, cryogenically mills the raw material into a precursor powder, which is essentially free of oxides and other undesirable impurities. The precursor powder is formed into a pre-form using low cost, short residence time molding processes. Finally, the pre-form is exposed to a nitriding process to convert the pre-form into the aluminum nitride armor body. In this manner, the method avoids the use of high cost aluminum nitride as a starting material and avoids the need for the high cost, single axis densification processes of the prior art.
