Consolidation of thermites by pressing and sintering
Consolidated thermites can be used as chemical heat sources. Pressing and sintering, a power metallurgy technique, has been developed to consolidate thermite parts with uniform density, composition, and calorific output. These materials are safe to handle, machineable, and generate minimum gas pressure upon reaction. This technique consists of die pressing various compositions of blended thermite powders, then isostatic pressing the parts before sintering to ensure the uniform density of the thermite composites. Parts sintered at various temperatures were examined metallographically for compositional uniformity and to determine whether diffusion between the powders had occurred. Flexure and tensile strength values were obtained to determine the temperature range required to produce strong parts. The coordination of metallography and strength values for various compositions and sintering temperature resulted in data that were used to optimize the fabrication process. Consolidation of thermite by pressing and sintering was found to be a valid process for producing uniform, dense, strong thermite parts.
