金屬微成形技術已越來越廣泛被利用於工業產品之製作，而其所使用之材料的成本隨著厚度的縮小而提高。本文利用電解鎳箔與壓延鎳箔進行實驗，比較其在顯微組織、材料異向性的差異，並進行兩種材料之L型彎曲成形。結果發現，電解鎳箔之異向性影響較壓延鎳箔輕微；在600℃之退火熱處理後，電解鎳箔之晶粒較壓延鎳箔小。兩者進行L型彎曲成形後發現，回彈量會隨著厚度的降低而減少，將經退火熱處理後之材料進行L型彎曲，可有效改善70%左右之回彈量。此外，壓延鎳箔會因為材料方向性的關係影響其回彈，而電解鎳箔則在不同方向上之回彈呈現一致性。本文進行不同生產方式之鎳箔比較分析，比較之結果可為金屬微成形製程於使用材料之參考。

The demands of micro-forming process in modern manufacturing technology have increased in the past decade. However, the cost of materials in the micro-forming process has also increased with the decreased dimension of parts. In this study, the microstructure, plastic strain ratio (r-value) and spring-back of nickel foils fabricated in two different ways, electrodeposited(ED) nickel foils and rolled nickel foils are described. The thickness of electrodeposited nickel foils used were 0.05mm, 0.075mm and 0.1mm respectively. The thickness of rolled nickel foils used were 0.05mm and 0.1mm. In the results, the plastic strain ratio of ED nickel foils showed lower anisotropy than rolled nickel foils. Moreover, the spring-back angel of rolled nickel foils was affected by the rolling direction but the ED nickel foils showed good consistence of spring-back in varied direction.
