HOT-PRESSED AND ROLL-REDUCED COMPACTS OF ALLOY Ti-6% Al-4%V POWDER RECOVERED FROM WROUGHT METAL SCRAP
Technical Report
·
OSTI ID:4268518
Massive scrap of alloy Ti--6%Al-4%V was embrittled with hydrogen and comminuted to powder of metallurgical quality. Compacts of this powder, hot pressed to theoretical density, closely approximated the original composition in chemistry. Whereas tensile properties of the hot-pressed compacts showed equivalent strength and somewhat lower ductility, compacts hot-roll-reduced developed higher strengths and ductility than the commercial mill-annealed wrought metal. Sustained loading at 800 deg E to a stress of 65,000 psi for 150 hours caused age hardening to circa 200,000 psi tensile strength with 7% elongation. (auth)
