Microstructure Uniformity and Mechanical Property Fluctuations in Large-Size Ti-46Al-8Nb-2.5V Ingot with β Solidification Mode

A large-size ingot (Φ200 mm × 800 mm) with the nominal composition Ti-46Al-8Nb-2.5V (in at.%) was fabricated via triple vacuum consumable electrode arc remelting in this study. XRD, SEM-EDS, TEM, tensile testing, and chemical analysis were employed to examine phase composition, m...
