Kelly as in Kelly and Groves

That book got me through my first year exams

That said, it still depends largely on the degree of cold working which provides the driving force for recrystallisation.

Remember, we do have data for the difference in electrical conductivity for cold drawn copper and soft copper, a difference of just over 10%.

Greater stored energy due to cold working will provide a greater drving force for recrystallisation, increasing the nucleation rate, resulting in a finer microstructure, which would probably not have as high a conductivity as a similar sample recrystallised from a lower state of cold working.
