• 中文摘要： 自行燃燒合成反應（Combustion Synthesis）是現代製成金屬、陶瓷、複合材料的新式方法。這種利用放熱反應的製成技術，解決了傳統粉末冶金耗時和耗能量的缺點。本文除了討論了自行燃燒合成的各種起始變數對製成物的影響，同時也介紹如何改變這些變數，控制製成物形狀的精確性，特質的一致性及稠密性。除此之外，新的製程參考圖（Processing Map）觀念，提供完整設計及製程的資訊，使得可以從起始變數的資料中，預測了製成物的特性。
• 英文摘要： Combustion synthesis, also referred to as micropyretic synthesis or self-propagating high-tem-perature synthesis (SHS), of powder compacts is a novel processing technique for the production ofintermetallics, engineering ceramics, and composites. The technique employs exothermic reactionprocessing, which circumvents difficulties associated with conventional powder metallurgical meth-ods of time and energy-intensive sinter processing. The synthesized products are influenced by thevarious initial processing parameters. These parameters include the chemical composition, compac-tion pressure, reactant size, and thermal environment of the unreacted compact. The homogeneousproperties and net shape are the fundamental requirements for the engineered product. The correla-tion of the initial processing parameters with the dimensional changes and homogeneous structures ofthe net-shaped product is discussed. The method for densification of the synthesized product is alsointroduced. The knowledge of the relationship between the initial parameters and final properties canbe used to generate the processing maps for combustion synthesis．These processing maps are ex-pected to become useful for the design procedures involved in the manufacture of combustion syn-thesized materials. An example of the Ni-Al system for the use of the processing maps is illustrated.
