Does anyone know at what temperatures cold working works best? I know that it depends on the type of material but there surely must be an approximate value?
Apparently cold working often has a negative effect on electric conductivity and I would like to know why and if it correlates to the degree of temperature. Any guesses? I read here (https://www.edelstahl-haerten.de/en/glossar/cold-working/) that cold working operates at temperatures far below recrystallisation temperature, but that range is quite large, innit?
Would love your input on this one, thank you!
Cold working can be expected
Cold working can be expected to introduce lattice defects, and any sort of lattice defect can be expected to scatter charge carriers. I'd expect an additional contribution to the electrical resistivity, essentially independent of temperature. At higher temperatures, annealing may relieve the damage.
