Some of the earliest characterization of steady-state creep in aluminum, was developed at UC Berkeley by John Dorn, his students and postdoctoral scholars, one being K.L. Murty. Research of the group included classic five power-law creep, Harper-Dorn creep, power-law breakdown and viscous glide. Many of the models and theories persisted for a relat...

This study examined the through-thickness ( z -direction) compressive stress versus strain behavior of 99.76% commercially pure (grade II) titanium sheet with relatively small grain size. The current study complemented earlier compression studies by examining a very thin (1.60 mm) sheet and deforming the Ti by successive compression tests to relati...

Many crystalline materials are known to exhibit creep at low temperatures (T < 0.3T m). Here, we review and analyze the phenomenological relationships that describe primary creep. The discussion focuses on the controversy as to whether power-law or logarithmic descriptions better describe the experimental database. We compile data from the literatu...

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-tempera...
