Partitioning Reactions to Control and Develop Unique Microstructures

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)
