Summary
Creep tests have been performed at temperatures above −10°C. The secondary creep behaviour can be described by a relation of the type\(\dot \gamma = B\tau ^n \) where\(\dot \gamma \) is the effective shear strain rate,τ the effective shear stress andB andn are constants.
n has a value close to 3 for stresses ranging from 0,8 kgf/cm2 to 5 kgf/cm2. Oscillatory creep rates have been observed during the tertiary creep, resulting from periodic processes of recrystallisation.
