Evaluation of Compatible Titanium Alloys in Boron Filament Composites.

Abstract

Development of a compatible titanium alloy for boron reinforced composites was completed successfully with the alloy Ti-13V-10M0-5Zr-2.5Al (Ti 1310). Properties are typical for beta alloys. Reaction rates with boron were found to be in excess of values predicted from initial research work but are adequate for primary and secondary fabrication yet leave life available for long-term (e.g., 10,000 hour) service application at 1000F. Roll-bonded two-ply tape of 25 percent boron and three-ply press-bonded sheet of 27 percent boron showed rule-of-mixture elastic moduli with strengths corresponding to failure strains of 0.006 inch/inch. Typical fabrication parameters for press bonding are 1520 degrees F/16 ksi/30 minutes. Fabrication of roll-bonded tape is a Solar developed process using higher temperatures for much shorter times (approximately 1800 degrees F for 1 second). (Author Modified Abstract)
