High Performance Brittle Matrices and Brittle Matrix Composites. Book 2

Abstract

The primary intent of this research was the development of composites having an acceptable combination of toughness and oxidation resistance. The research was closely coordinated with the DARPA/ONR URI program as UCSB concerned with high temperature, high performance composites. The study comprised three tasks. The first task was to study phase equilibria, solidification pathways and toughness properties of intermetallics, such as oxidation resistance Ti-Al-Ta and Nb-Al-Si alloys, and ceramics. These studies were then combined with interface interaction studies between the matrix microstructure and ductilizing/toughening particulates and fibers. The second task was a basic study of interface structure and chemistry as it relates to the mechanical properties of the interface. The third task involved studies on aluminum and copper matrix composites. These studies were concerned with developing an understanding of creep resistance. (JES)
