Titanium aluminides: science, technology, applications and synthesis by mechanical alloying

The production, characteristics, and commercialization of monolithic and composite titanium aluminides are summarized with emphasis on use in the demanding aerospace industry. The attractive elevated temperature properties combined with a low density make these materials of great interest, but inherently low 'forgiveness', and environmental concerns, must be overcome before widespread use will occur. One synthesis method for the production of monolithic titanium aluminides-mechanical alloying-will be discussed in detail.
