Diffraction study of self-recovery in decomposed Al2TiO 5during vacuum annealing

Conference Paper


Abstract


  • The ability of decomposed Al2TiO5 to undergo self-recovery or reformation during vacuum annealing was characterised by in-situ neutron diffraction. It is shown that the process of phase decomposition in Al2TiO5 was reversible and that reformation occurred readily when decomposed Al2TiO5 was re-heated above 1300��C. The kinetics of isothermal and temperature-dependent self-recovery was modelled using the Avrami equation. The influence of grain-size on the Avramic kinetics of self-recovery was also evident.
