Abstract:

Studies reported include 1 Liquid precursor formulation, pyrolysis, compositional homogeneity, and densification, 2 Crystallization vs. composition subsequent to pyrolysis, 3 High temperature phase partitioning of metastable structures produced during crystallization after pyrolysis, 4 Grain growth phenomena as related to different binary, solid-solution cations and composition with different binary systems, 5 Microstructural instabilities of polycrystalline thin films, 6 Microstructural instabilities of polycrystalline fibers constrained by composite matrices, 7 Formation of single crystal thin films as a function of differential composition and lattice mismatch, and 8 Relations between processing flaws and strength for fibers produced by dry spinning. The pertinent results of these studies and their interrelations are summarized. JS
