Superplasticity of Nanocrystalline ZrO2-Spinel Composite

摘要:

文章预览

The effect of nanocrystalization on superplastic flow was examined in ZrO2-30vol%spinel composite. The nanocrystalization can increase the strain rate by one order of magnitude or lower the deforming temperature by about 100 K. Irrespective of the lowered flow stress, however, the tensile elongation to failure of nanocrystalline composite is lower than that of submicrom-grain composite. The limited tensile elongation in nanocrystalline composite can be ascribed mainly to accelerating cavity damage accumulation.
