現代化的產品設計中，常於有限的空間與重量限制下，要求同時具有高性能且多功能的需求，而金屬材料因其具有優良的結構性、導電性與導熱性，故在許多先進與高科技產業之現代化產品設計中，扮演相當重要的角色，但單一金屬往往無法於特定空間限制下，又同時需滿足多元化的功能需求，故複合金屬的組合設計，創造了許多彈性且富創意的複合應用空間。
而銅，其具有極佳的導電與導熱性能優勢，鋁則是以相當的輕量化結構並兼具良好的導熱與導電性能著稱; 故以鋁、銅之同質異型、異質同型、異質異型的各種不同材料組合與型式組合之複合金屬，其充滿創新模式的應用設計因應而生;　而亦因其均具極佳的導熱性，故如以傳統的銲接工法以建立複合金屬，則存在著相當的製程控制困難、品質控制不佳，連續化的生產更難以完成。
基於解決此高難度，高導熱導電的鋁與銅的複合製程技術，本研究的主要目的有三大主題，其一為建立高導熱金屬間的最適化複合製程參數設計，其二為研究設計不間斷金屬製程的連續化接頭與製程，其三為設計開發金屬表面的高溫不變色金屬質感保持技術。
而本研究提出之創新製程與控制參數方法，為新增差異化的熱前處理製程段，形成新型的四段式軋延接合製程，可建立異質接合與同質接合的最適化製程控制參數，形成可連續化之高品質的高導熱金屬複合；並以金屬高分子的複合法成功的創造金屬之高溫的防變色技術。
本研究提出的製程設計與參數控制法, 對未來更先進與多功能的產品開發中,進行異質或同質金屬複合、金屬連續化與金屬質感保持，會有實際性的助益。

The aim is to develop an uninterrupted processing route to manufacture metal coils, so that the efficiency of production, as well as the quality of the product and the cost-efficiency can be improved. The traditional method of joining two metal sheets is by welding; however the welding process itself can easily introduce additional processing steps and pile up the cost of production. In the past, joining two metal sheets with identical composition by the rolling process has not been easy. The present study induces dissimilarity between two sheets, i.e. pre-heat treatment for one plate to result grain growth. Experimental results indicate that such introduction of dissimilarity between two metal parts can significantly improve the roll bonding process, not only making the joint much stronger than the traditional welding technique, this newly developed method can enhance the efficiency of the production of metal coils in industries.
In present study, a quantitative analytical approach has been taken to evaluate means to protect copper alloys (nickel silvers) against surface discoloration under the exposure of high temperatures. The aim is to propose future direction to further improve the surface protection against oxidation for nickel silver plates. Two approaches have been taken: one is to apply surface coating, another is to refine the subsurface grain structure in the bare substrate. Samples of nickel silver with and without surface coatings were exposed to 300。C and 350。C, respectively, for 10 mintues. Tested samples were then subjected to spectral colorimeter studies; phase identifications were examined by XRD. In addition, the coating procedures were carefully studied in order to determine the optimal processing parameters for yielding the maximum protection. In conclusions, coating thickness does not affect the resistance against discoloration, pre-treatment of the substrate surfaces as well as the concentration and soak time of the anti-discoloration solutions can greatly influence the performances of the entire system against the occurrence of surface discoloration.
