dc.description.abstract | 本研究主要以Ti15Cu15Ni與Ti50Ni填料進行同質與異質真空硬焊鋯金屬為主。在鋯金屬對鋯金屬同質接合的實驗中,由不同硬焊溫度的結果可以知道,當有Zr元素融熔進入填料合金後,可以將硬焊的溫度下降最多95K。經由接合介面的顯微組織分析,可以得知焊道中的組成變化與持溫時間有顯著的關連。在300~600s的短時間硬焊製程中,焊道中主要存在的相為Zr-rich相、TiZrNi相等多種相所組成的共晶組織。而在1800s較長的製程時間下,母材經由溶解進入合金填料的比例上升,造成焊道寬度從50μm增加到100μm。在3600s的製程時間下,填料合金元素亦可經由擴散進入基材造成共晶相的消失,僅有少量殘存的TiZrNi相存在。至於在鈦金屬 – 鋯金屬硬焊接合,焊道中主要的相為TiZrNi、Ti-rich 、Zr-rich與不規則形狀的共晶所組成。在Ti6Al4V – 鋯金屬硬焊接合,焊道中主要的相為TiZrNi、Zr-rich 與不規則的共晶組織。最後,在缺少銅元素的填料下仍能在較低的溫度進行硬焊,是因為大量的鋯元素也可充當溫度降低的元素而有液體產生。 | zh_TW |
dc.description.abstract | Both similar and dissimilar joining of Zr metal was studied in this research. The dissolution of Zr substrate into the molten braze resulted in decreasing the brazing temperature to 1123K. Based on the SEM and EPMA analyses, microstructures of brazed joints strongly depended on the brazing time. For the shorter brazing time periods, 300s ~ 600s, the brazed joints mainly consist of the Zr-rich phase, TiZrNi intermetallic compound and eutectic structure. For the longer brazing time period, 1800s, huge amount of Zr was dissolved into the brazed zone, and the width of brazed joint increased from 50μm to 100μm. For the 3600s brazed joint, alloying elements in the filler metal diffused into the base metal, making the eutectic disappear from the joint and remaining TiZrNi intermetallic phase. For the joining of Ti and Zr, primary phases in brazed zone were TiZrNi, Zr-rich, Ti-rich and eutectic. For the joining of Ti6Al4V and Zr, major phases in brazed zone are TiZrNi、Zr-rich and eutectic. Finally, the brazing was still workable for the filler metal free of Cu. It is observed that huge amount of Zr were dissolved in the brazed joint, served as the melting point depressant of the brazing filler and resulted in formation of liquid in lower temperature. | en |
