In-Situ Eutectic High-Temperature TI-Based Composites

Abstract

This report results from a contract tasking Francevych Institute for Problems of Materials Science as follows: The contractor shall investigate cast Ti-Si-X and Ti-B-X eutectic alloys. Emphasis shall be placed on investigating the structure and physico-mechanical properties (strength, fracture toughness, long term high temperature hardness etc) in a range from room temperature up to 1000 degrees C. Composites will be varied in composition and volume content of reinforcing phases and matrix to find the best combination of heat resistance and fracture toughness, with a final selection and optimization of compositions which are most promising for high-temperature applications. The contractor shall emphasize a low-cost approach for producing materials throughout the research with arc- or electron-beam melting, focusing on existing experimental alloys which can be improved by optimizing the structural parameters of the composites and phase and chemical compositions of the constituent phases.
