Distinctive ductility anisotropy induced by keyhole pores in Y2O3-reinforced high-temperature titanium alloy fabricated by additive manufacturing

Key Points

• Distinctive ductility anisotropy is observed in high-temperature titanium alloys with keyhole pores.
• The presence of keyhole pores significantly influences the mechanical properties, particularly ductility.
• Additive manufacturing techniques were employed to create Y2O3-reinforced titanium alloys.
• Findings suggest that understanding pore effects could enhance material performance in engineering applications.
