Chapter 13 - Low-Temperature Creep Plasticity

Abstract

Temperature ranges for creep can be subdivided into three categories: high-temperature creep (T>0.6Tm), intermediate-temperature creep (0.3Tm<T<0.6Tm), and low-temperature creep (T<0.3Tm). Generally, creep studies investigate high-temperature deformation; however, this chapter reviews the latter category. Less attention has been paid to low-temperature creep due to the fact that materials generally neither fail nor experience significant plasticity at lower (especially ambient and cryogenic) temperatures.
