摘要註:	本研究之目的為探討含銀2205雙相不銹鋼其γ'相析出之溫度區間以及添加銀對顯微組織之影響。本實驗以2205雙相不銹鋼為材料，添加的銀含量分別為0.2 wt%。實驗內容分為兩個部分，首先針對不同時間的固溶處理(1200℃，進行0、2、4、6、8、10、12小時)對於高溫顯微組織變化以及添加銀後的顯微組織變化作探討，再經由不同溫度時效熱處理觀察γ'相析出之溫度區間和銀對析出物析出之影響。從實驗結果可發現固溶處理隨著時間增加，γ'相會逐漸消失，而肥粒鐵含量會先減少然後接著再增加。當固溶到12小時，γ'相則幾乎不存在。經EPMA的定量分析可得知隨固溶時間的增加，銀會溶於相組織中，銀於δ相與γ相之溶解度皆約0.1wt%。此外，銀的添加有助於使γ'相於固溶處理溶解回δ基地相。對經固溶處理後之試片進行不同溫度的時效處理，可觀察到於900℃下進行2小時的時效處理會有χ相、σ相和γ2相析出，在800℃下則只有χ相與γ2相，而銀顆粒可為χ相之成核點。γ'相析出溫度區間方面，未含銀2205雙相不銹鋼之γ'相析出的溫度在900~1000℃，而含銀2205雙相不銹鋼之γ'相析出的溫度則是在800~1000℃。在同溫度下不同時效時間之相變化的部分，γ'相會先以長條狀直接生成於δ基地相，接著變成細小顆粒狀，然後晶粒尺寸隨時效時間增加而增大。δ/γ相界之γ2可發現某些部份為針狀長條形態，且是垂直於γ相方向生長，隨時效時間增長而變大。時效2小時後，兩島狀γ相部份會相連接。 The purpose of this study is the precipitation temperature range of the γ' phase and the effect of doping silver on microstructure in 2205 duplex stainless steel. In this study, 2205 duplex stainless steels were selected as test materials, silver contents were 0wt% and 0.2wt%. Experiment was divided into two parts, the first part focuses on the effects of solid solution treatment with various time and silver adding on the variation of high temperature microstructure；the second part focuses on the precipitation temperature range of the γ' phase and effect of silver adding on the precipitation of the intermetallic phase with the different temperatures of aging treatment. From the experimental results of the first part, the γ' phase gradually disappeared with the increase of the solid solution time, while, the ferrite contents decreased first, then increased.. When the solid solution time was up to 12 hours, the γ' phase almost didn’t exist. In the quantitative analysis of EPMA, silver would dissolve in each phase with increasing solid solution time, and the solubility of silver in the δ and γ phase was approximately 0.1 wt% for 12 hours of the solid solution. In addition, both the solid solution treatment and adding silver could let the γ phase coarsen, and doping silver also benefited to dissolve γ' phase faster in the material. From the experiments of the second part, the results showed that the materials would observe the χ phase, σ phase and γ2 phase after the aging treatment was at 900℃. When the aging temperature at 800℃, the precipitates only had χ and γ2 phase. The Ag particles could be the nucleation sites of the χ phase. In the precipitation temperature range of the γ' phase, the great amount of γ' phase generated in 2205 duplex stainless steel while the aging temperature in the period of 900~1000℃, and the great amount of γ' phase precipitated in silver-containing 2205 duplex stainless steels was 800~1000℃. In the phase transformation of the different aging time at 800℃ , the γ' phase firstly generated in the shape of banding, and next become to the fine particle. Then, some γ2 phase was needle-like column at δ/γ grain boundaries, and the growth direction was perpendicular to the γ phase. The grain size of the γ' and γ2 phase increased with increasing aging times. When the aging time in 2 hours, part of two island- γ phase would be connected.
