The Dislocation-Structure and Crystallite-Size in Forsterite (Olivine) Deformed at 1400℃ by 11 GPa

摘要

Synthetic forsterite samples were shear-deformed at 11 GPa, 1400℃ in the mul-tianvil apparatus. The deformation microstructures have been characterised by x-ray diffraction peak broadening and strain anisotropy analysis. The evolution of strain and stress are characterised as a function of the time duration of the high-pressure, high-temperature experiments.
