摘要：

Vickers hardness of nanocrystalline (N-) TiO2 was measured in the temperature range 25-degrees to 1200-degrees-C and it was compared with that of polycrystalline (P-) TiO2 in the same temperature range. N-TiO2 showed a lower hardness than P-TiO2 at temperatures up to 800-degrees-C which resulted in the lack of indentation crack traces for N-TiO2 presumably implying more plasticity.
