Abstract: An insensitive high explosive is obtained by using a dicyandiamide (DCDA), ammonium nitrate (AN), guanidine nitrate (GN), ethylene diamine dinitrate (EDDN) eutectic melt binder in combination with ammonium perchlorate (AP) oxidizer, fine RDX (1 .mu.m to 10 .mu.m particle size), and aluminum metal as a fuel. The fine RDX particles improve performance, boosterability, and sensitivity. The inclusion of AP greatly improves air blast by adding oxygen to the reaction and insuring complete combustion of the ingredients. The aluminum extends the pressure pulse. The ratio of materials is formulated to obtain the lowest known processing temperature.

Abstract: A method of manufacturing a flat form from blended metallic powder including a major constituent by weight having a high melting point and a minor constituent by weiht having a substantially lower melting point includes selection of the powder to provide continuous and reproducible compacted flat forms. Powder is selected on the basis of compressibility and flowability. The selected powder is compacted to a flat green form and then liquid phase sintered. The flat form may be stacked to provide a flat article of a desired thickness which will result in a monolithic or composite cross section when subsequently sintered. Liquid phase sintering is carried out in a manner designed to avoid undesirable embrittlement and to provide a uniform microstructure in the fully consolidated article. The process is especially useful in the production of tungsten heavy alloy plate.

Abstract: This invention provides a solid explosive composition comprising a low-water content melt-in-fuel emulsion when prepared at elevated temperature which solidifies on cooling. The emulsion comprises a continuous phase containing water immiscible fuel and emulsifier and a discontinuous phase containing oxidizer salt. A particulate material effective as a nucleating agent is incorporated in the composition to reduce supercooling of the discontinuous phase and to accelerate crystallization of the oxidizer salt.The particulate nucleating agent is preferably colloidal solid particles for example silica or an insoluble salt of aluminium, calcium or barium, which salt may optionally be formed in situ by a double decomposition reaction.The presence of the nucleating agent to accelerate crystallization of the oxidizer enhances the proportion of discrete droplets which remain totally encapsulated in the solidified composition and enables solid products to be obtained from relatively low melting oxidizer salts melts.
