Abstract
A method and an exothermic composition for controlled localized heating of a base material, said composition comprising an exothermic mixture material, a binder material, and optional filler and starter materials, said exothermic mixture material having a predetermined temperature of burning, said binder material providing said composition in a preformed shape when processed with said exothermic material mixture. Self-propagating high-temperature synthesis (SHS) materials are used as preferred exothermic materials. These compositions can be used for a variety of industrial purposes such as cutting, welding, or coating of various materials.
