Dislocation recovery in fine-grained polycrystalline olivine

Farla, Robert; Kokkonen, Harri; Fitz Gerald, John; Barnhoorn, Auke; Faul, Ulrich H; Jackson, Ian


The rate of static dislocation recovery in Fo90 olivine has been studied under conditions of high temperature and controlled atmosphere in compressively deformed polycrystals hot-pressed from synthetic (sol-gel) and natural (San Carlos) precursor powders. The sol-gel olivine, containing a small fraction of orthopyroxene, was deformed to a final strain of 19% with a maximum differential stress of 266 MPa whereas the San Carlos specimen was deformed to 15% strain and 260 MPa differential stress....[Show more]
