摘要

為條理出製程參數之函數關系，作為開發雙金屬固態輥壓接合新製程之參考，本文在既有之滑線場理論基礎上試從磨潤熱力學之角度探討雙金屬輥壓製程中母材介面之質互動問題。步驟上係從力學模型導入固態接合機制之物理化學本構關系，討論的重點放在微觀質能互動之初條件上。其後再著眼此複合加工製程之一般理論開發所需之數學模型的建構原則。介觀塑性力學理論體系本構關係之新理論與研究方向藉此提出。

With an aim to identify dominating processing factors as well as their functional relationship thus to facilitate novel bimetal roll-bond process development, this work presents the problem of bimetal roll-bond process on the base of slip line fields theory through tribo-thermodynamics. By establishing first a physical model that deal with the constitutive relation governing the physical chemical mechanisms of solid phase bonding derived from mechanics model, emphasis is placed on exploring initial microscopic materials-energy interacting conditions. After which, principles in establishing an unified theory for mathematical modeling are explored. A novel mesoplasticity theory and research direction is thus advanced.
