Dynamic recrystallization of olivine single crystals during high-temperature creep
Abstract
High-temperature creep experiments were made on olivine single crystals under compressional stress to large strains. At strains larger than about 40 to 60%, dynamic recrystllization occurs and cellular wall dislocation structure is formed. Recrystallized grain size dg(µm) and cell wall spacing ds(µm) are dependent upon applied stress σ(MPa) as: FD1 dg=(8.3-3.1+5.0)×103σ-1.18±0.11 and FD2 ds=(2.8-1.0+1.5)×102σ-0.67±0.10
