Understanding the effect of scanning strategies on the microstructure and crystallographic texture of Ti-6Al-4V alloy manufactured by laser powder bed fusion

Jiangwei Liu et al.

Summary: This study investigates the influence of different scanning strategies on the microstructure, crystallographic texture, and phase composition of Ti-6Al-4V alloy manufactured by Laser Powder Bed Fusion (LPBF) through experimental and numerical methods. The findings suggest that scanning strategies lead to diverse microstructural features and phase compositions in LPBF-built samples, providing a route towards tailoring mechanical properties and isotropic behaviors in additive manufacturing.

Charpy impact anisotropy and the associated mechanisms in a hot-rolled Ti-6Al-3Nb-2Zr-1Mo alloy plate

Junqiang Ren et al.

Summary: In this study, strong anisotropic variations in impact absorption energies of a hot-rolled Ti-6Al-3Nb-2Zr-1Mo alloy plate with different sampling and notching directions were observed. The higher crack propagation energy of the RD-ND sample resulted in significantly larger impact absorption energy compared to other samples. Analysis revealed that the higher absorption energy of the RD-ND sample was attributed to the activities of prismatic slips and the resistance created by grain boundaries against crack propagation. The coupling effect of crystallographic texture and microstructural characteristics on the impact deformation mechanisms of the alloy was also described.

Crack propagation during Charpy impact toughness testing of Ti-Al-V-Mo-Zr alloy tubes containing equiaxed and lamellar microstructures

Guangfang Chi et al.

Summary: The study investigated the impact toughness of a Ti-Al-V-Mo-Zr alloy under different heat treatment parameters, revealing that solid solution and aging treatments can decrease impact toughness while subcritical annealing and slow cooling can increase it. The direction of crack propagation was towards low-angle boundary regions, and a dissolved secondary phase near the fracture surface enhanced the alloy's resistance to crack propagation.

Impact toughness and deformation modes of Ti-6Al-4V alloy with different microstructures

Lei Lei et al.

Summary: The impact toughness of Ti-6Al-4V alloy with different microstructures was studied, with the bimodal microstructure (BM) showing the highest impact toughness due to a composite-like structure containing hard primary alpha grain and soft beta transformation microstructure. In contrast, the fine and coarse lamellar microstructures (LM1 and LM2) exhibited lower impact toughness due to limited plastic deformation and heterogeneous deformation, respectively. Coordination of deformation abilities within the microstructure was found to play a key role in impact toughness of the alloy.

Microstructure tailoring and impact toughness of a newly developed high strength Ti-5Al-3Mo-3V-2Cr-2Zr-1Nb-1Fe alloy

Cong Wu et al.

Summary: Samples with different microstructures (BM, TM, LM) of a high strength Ti-5321 alloy were tested for impact performance, with results showing that LM had the highest impact toughness and crack initiation energy. SEM and EBSD analysis revealed the influence of microstructure on crack initiation and propagation during impact process, indicating that LM exhibited better impact properties due to its specific microstructure characteristics.

Toughening effects of Mo and Nb addition on impact toughness and crack resistance of titanium alloys

Shixing Huang et al.

Summary: The addition of beta stabilizers Mo and Nb significantly improved the impact toughness and crack resistance of titanium alloys. Ti-6Al-2Mo and Ti-6Al-3Nb alloys exhibited higher impact toughness and stronger resistance to crack propagation compared to Ti-6Al due to increased dislocation density and deformation twinning. This was attributed to the enhanced dislocation mobility and nucleation of deformation twinning in alpha/beta interfaces, leading to larger plastic deformation under impact loading.

Feipeng An et al.

Summary: The study investigated the effects of vanadium content on the microstructure, tensile properties and impact toughness of Ti-6Al-xV alloys prepared by Wire + Arc Additive Manufacturing (WAAM). Ti-6Al and Ti-6Al-2V alloys exhibited better matching of strength, ductility and impact toughness compared with Ti-6Al-4V alloy, with a monotonic increase in yield strength and ultimate tensile strength observed with increasing vanadium content.
