Low temperature creep plasticity

Abstract

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 at T < 0.3Tm is discussed in terms of the context of higher temperature activation energy. The basic mechanism(s) of low temperature creep plasticity are discussed, as well.
