小行星9411477 本研究的目的是研究一种新的方法，通过产生“单相层压材料”来增韧单相材料而不添加第二相。“用于研究的原型材料是钛酸铁，其沿着一个轴具有极低的热膨胀系数。 陶瓷中的纹理可以通过磁场辅助技术来开发。 建议的研究包括基本的断裂研究的钛酸铁，随机和纹理，单片和层压，以获得理解微观结构加工关系。 原位小角度微裂纹。 最后，将通过层压显微结构为坚韧单相陶瓷建立设计准则。 %%% 本研究将探索一种新的方法，在不添加第二相的情况下增韧单相材料钛酸铁。 织构化材料将在磁场处理的辅助下进行处理。 本课程将建立对显微结构与工艺关系的理解，以及通过层压显微结构设计坚韧单相陶瓷的准则。 ***

9411477 Faber It is the intent of this proposed work to examine a novel approach to toughening single phase materials without second phase addition by creation of "single phase laminates." The prototype material for study is iron titanate with an exceedingly low thermal expansion coefficient along one of its axes. Textures in the ceramics can be developed through magnetic field assisted techniques. The studies proposed consists of fundamental fracture studies of iron titanate, both random and textured, monolithic and laminated, to gain an understanding microstructure-processing relationships. Small angle microcracking in situ. Finally the design criteria will be established for tough, single phase ceramics through laminated microstructures. %%% The proposed work will examine a novel approach to toughening single phase materials iron titanate without second phase addition. The textured material will be processed with the assistance of magnetic field processing. An understanding of microstructure- processing relationship and the design criteria for tough, single phase ceramic through laminated microstructure will be established. ***
