Changes of the elastic modulus (E) and the hardness (H) are related to increasing longrange order and vanishing amorphous interface areas. Metamict titanite shows H and E values close to titanite glass. H decreases on annealing until ca. 950 K. to 9.08 GPa and increases at higher temperatures, while E increases continuously on annealing up to ca. 168.4 GPa at 1220K. Crystalline titanite from Rauris shows strong anisotropy and H and E values are clearly larger than those of E2312. 1029-0338.en0141-1594201212332Taylor & FrancisMetamictNanoindentationSynchrotron XRDTitaniteChemieJournal Article10.1080/01411594.2012.694433Journal Article
