摘 要
本實驗為快速超塑成形，在不同成形條件下探討厚度減少量和空孔率的關係。成形採用之材料為超塑性5083鋁鎂合金。其成形條件分下列三個部份：
( 1 ) 相同成形溫度下 ( 分別為400℃、450℃、500℃ )，有相同有效成形壓力梯度，施與沒有背壓和有背壓成形。
( 2 ) 成形溫度500℃沒有背壓下，不同的有效成形壓力梯度不同完全成形時間。
( 3 ) 成形溫度500℃沒有背壓下，其有效成形壓力梯度和 ( 1 ) 中500℃沒有背壓相同，鈑片不同潤滑劑塗佈方式。
以不同主題去討論上述這三個部份，並得到結論。
相同成形溫度，相同有效成形壓力 ( 上模和下模的壓差 ) ，成形時間沒有背壓大於有背壓。當提高初始有效成形壓力值，會縮短成形時間。
在快速超塑性成形的過程中，成形鈑片的厚度減少量和有效應變是正相關，同時落在一趨勢線上。
由本實驗中，快速超塑成形SP – 5083的建議成形條件為：成形溫度500℃，觸底前不施與背壓，觸底後施與背壓成形。
