1/d decreases (i.e. the grain size increases), the metal diffusion would decrease since there are less fast diffusion paths available. This would result in a higher MTTF as 1/d decreases. And as the line width, w, decreases, one might expect that there is more chance for a void to span across the whole line resulting in an open circuit.

High pressure grinding rolls (HPGR)

High pressure grinding rolls (HPGR) are used for size reduction or rocks and ores. They compress the feed material between two rotating rollers, one of which is in a fixed position and another roller that is floating. The two rotating rollers generate such a high pressure that it grinds the feed material to the desired smaller grain size.
