| Outline of Final Research Achievements |
In order to utilize energy-saving bonding technology for wiring of electronic devices and metal structure and also as a heat source in special environment such as space and under the sea, we developed metal powder materials with self-propagating exothermic reaction. Using cold-rolling and pulverizing method with aluminium and nickel foils, we succeeded in producing exothermic powder exhibiting very high temperature over 1500°C in 0.1msec. As a result of detailed experiments and analysis, we found that controlling the production conditions of cold-rolling is able to control the exothermic reaction characteristics. Moreover, using this developed powder materials, we also succeeded in joining aluminium foils and copper wire experimentally.

| Academic Significance and Societal Importance of the Research Achievements |
本研究において開発した発熱粉末材料は，燃焼ではなく化学反応による発熱を示すことから，任意の環境で局所加熱できる事が可能であるだけでなく，不必要なエネルギーを使わずに且つ熱ダメージを最小限にできる有効な技術となりうる可能性を示している．加えてmsecオーダーの極短時間における発熱特性や結晶構造変化を捉える評価技術は，実際の化学反応現象を理解する上で必要不可欠な技術であり，本材料以外にも発展的な利用が期待できる．
