Abstract

Ti-22Al-27Nb specimens of different microstructures were exposed to both cathodic and gaseous hydrogen charging. Lattice parameters of the ordered orthorhombic (O) phase and the bcc (β₀) phase were determined using X-ray diffractometry. Neither cracks nor microstructural changes were found after cathodic hydrogen charging at 1 A/cm² for 168 h. No cracking was found after gaseous hydrogen charging (4 bar, 1h) at temperatures below 500°C, and little cracking at temperatures above 500°C as compared to Ti-25Al-10Nb-3V-1Mo. These results suggest that Ti-22Al-27Nb may have good resistance to hydrogen. Gaseous hydrogen charging resulted in changes in the X-ray diffraction pattern, showing that Al₁₅H₂Ti₁₅ hydride had been formed.
