Grain structure of thin electrodeposited and rolled copper ...

Dec 01, 2004· Increasing the foil thickness results in a large grain size tail and an enhanced spread of grain sizes. The anneal exposure widens this spread, doing so more effectively for the thinner foils. The 12-μm foil is especially amenable to annealing; in the post-anneal state, it develops a considerable range of grain sizes (0.1–1.5 μm).
