Films constrained sintering

Although assumptions of ideal material properties such as linear elasticity and isotropy were considered during simulations of the 3D reconstructed microstructures, the isotropy of the actual microstructures remained questioned. One of the factors responsible for the fact that the microstructures of the films could not possibly be ideally isotropic was that the films experienced constrained sintering which induced greater lateral shrinkage/densification across the direction normal to the surface than that in the other two directions which might result in non-identical... [Pg.122]

When the constrained film is sintered for times longer than those shown in the figure, the density is found to increase steadily and eventually reach the same final value as the free film. [Pg.729]

A theoretical framework is developed to predict curvature of sintering thin film deposited on presintered substrate for three different heating rates as a way for validating a constrained sintering model developed recently. Using universal expression for free sintering rate and viscosity and estimating... [Pg.80]

This equation correlates the densification rate of a constrained film, Sz, with the densification rate of a free sintered body, e/, via the viscous Poisson s ratio, Vp. As the grain size is comparable to the thickness of a thin film, however,... [Pg.75]

The data for the sintering of the polycrystalline ZnO films are shown in Fig. 11.34. In this case, the constrained film sinters considerably more slowly than the free film and even after prolonged sintering does not reach the same end-point density as the free film. Instead, the shrinkage reaches a steady value that is considerably lower than that reached by the free film. The data for the AI2O3 films showed trends similar to those for the ZnO films. [Pg.729]

Figure 11.33 Isothermal shrinkage data for constrained and free glass films sintered at 650°C. The curve through the data for the free film represents the best fit to the data using Scherer s model for viscous sintering. The curve through the data for the constrained film represents the fit to the data by the thin-fihn model of Scherer and Garino using the fitting constants derived from the fit to the free-film data. (From Ref. 47.)... Figure 11.33 Isothermal shrinkage data for constrained and free glass films sintered at 650°C.
