Effect of Interface Properties on Microcracking of Iron Titanate

Appropriately tailored interfaces at the grain boundaries can be used to reduce the residual stresses that are generated from thermal mismatch strains during cooling from the fabrication temperature to room temperature due to thermal expansion anisotropy. Interfaces with higher coefficient of therma...

Description
Summary:Appropriately tailored interfaces at the grain boundaries can be used to reduce the residual stresses that are generated from thermal mismatch strains during cooling from the fabrication temperature to room temperature due to thermal expansion anisotropy. Interfaces with higher coefficient of thermal expansion are most effective in reducing residual stresses in Fe sub 2 TiO sub 5 grains and those with lower stiffness in reducing the residual stresses in the interface. In both cases, these conditions reduce the overall propensity for spontaneous microcracking.
