| 中文摘要 |
本研究分別利用冷模連鑄和熱模連鑄兩種製程將高純度銀材製成銀線。經測試結果，連鑄銀線可保留既有之純度，並降低含氧量。透過調整製程參數，連鑄銀線之顯微組織發生改變。冷模連鑄銀線晶粒沿熱流方向成長，晶粒間以高角度晶界為主。在引拔速度較慢時晶粒數量少，線芯晶粒尺寸明顯大於表面，晶體主要沿＜111＞方向生長，隨引拔速度上升，截面上晶粒趨於等軸，晶粒尺寸落差下降；熱模連鑄銀線顯微結構則呈現與熱流方向平行之柱狀晶粒，晶粒間以低角度晶界為主，晶體主要生長方向為＜100＞，在適當參數配合下可製備接近單晶的銀線，截面上晶界數量極少。 |
| 英文摘要 |
In this study, cold-mold and hot-mold continuous castings are employed to produce high purity silver wires. The continuous cast wires retain their purity. By adjusting the casting processes the microstructures of silver wires varied. The silver wire grains produced by cold die casting grow in the direction of the heat flow, with high angle grain boundaries among grains. The silver casting by cold mold grow along <111> direction. When the casting speed is low, the grain size in the wire core is significantly larger than that on the surface. As the drawing speed rises, the grains gradually change to uniform equiaxial crystals. The microstructure of the silver casting in the hot-mold shows columnar crystals parallel to the direction of heat flow in a <100> growth direction. With the appropriate experimental parameters, nearly single crystal silver wires could be produced. |
