If I understand that correctly, to maintain a constant Deborah number with a piece of hot or cold steel, the rate of deformation would have to be much slower for the piece of cold steel compared to that of the the hot steel. Correct?
Is it true that even though steel is not exactly what I would consider a fluid, apparently it can actually relax enough over some period of time that fatigue could occur without hardening?
Practically, what period of deformation are we talking about with room temperature stainless steel to induce hardening? 1 per second? Five/second? 1/month?
