Low temperature creep plasticity

摘要

The creep behavior of crystalline materials at low temperatures (T<0.3Tm) is discussed. In particular, the phenomenological relationships that describe primary creep are reviewed and analyzed. A discussion of the activation energy for creep atT<0.3Tmis discussed in terms of the context of higher temperature activation energy. The basic mechanism(s) of low temperature creep plasticity are discussed, as well.
