Constrained sintering thin films

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]

Figure 11.13 Examples of constrained sintering (a) a composite in which inclusions prevent the powder matrix form sintering freely (b) an adherent thin film for which sintering in the plane of the film is inhibited by the substrate (c) a multilayer in which the layers sinter at different rates.

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.
