Dynamic α globularization in laser powder bed fusion additively manufactured Ti-6Al-4V

Acta Materialia, Год журнала: 2023, Номер 255, С. 119076 - 119076

As a dual-phase α+β titanium alloy broadly used in the aerospace and biomedicine sectors, Ti-6Al-4V offers variety of attractive mechanical properties imparted by its tailorable microstructures typically developed via thermomechanical processing. Such capability microstructural control, however, is still beyond reach laser powder-bed fusion (LPBF) additive manufacturing (AM) Ti-6Al-4V. Here we demonstrate for first time development near-equiaxed α microstructure situ dynamic globularization as-built state LPBF Akin to during processing, process also governed series mechanisms such as sub-grain boundary formation, splitting, thermal grooving, lamellar termination migration epitaxial growth. This largely driven continuous introduction excess dislocations at mismatched α/β interphase boundaries while α↔β phase transformation takes place repeatedly LPBF. The findings this study provide new knowledge towards holistic control strategy additively manufactured

Precipitation kinetics of niobium carbide (NbC) during homogenization heat treatment of additively manufactured inconel 718 superalloy

Journal of Materials Research and Technology, Год журнала: 2023, Номер 25, С. 1774 - 1781

High cooling rate of the laser powder bed fusion (L-PBF) additive manufacturing can suppress formation niobium carbide (NbC) phase in fabricated Inconel 718 nickel-based superalloy parts. However, it might precipitate during elevated temperature exposure. Accordingly, present work, precipitation kinetics NbC was investigated homogenization heat treatment at temperatures range 1000–1150 °C for soaking times 15 min to 10 h. It observed that increasing leads faster formation. The modeled by general transformation formula (based on transformed fraction 0.5 or 50%, t0.5) and Johnson–Mehl–Avrami–Kolmogorov (JMAK) analysis, resulting activation energies 159.2 157.4 kJ/mol, respectively. concluded diffusion both C Nb atoms Ni matrix are underlying mechanisms treatment. relationship 1/t0.5∝exp(0.0097T) also obtained as a function temperature.
