Investigation on Anisotropic Mechanical Behavior of Ti-6Al-4V Alloy via Schmid Factor and Kernel Average Misorientation Distribution

Jinkui Meng et al.

Summary: The anisotropic behavior of the Ti-6Al-4V alloy was investigated through tensile tests along different directions. It was found that samples tensioned along the rolling direction and transverse direction showed similar yield strength, while samples tensioned along the diagonal direction had lower yield strength. The anisotropy of the Ti-6Al-4V sheet is closely related to its crystallographic texture.

Effect of content and configuration of equiaxed & alpha; and lamellar & alpha; on deformation mechanism and tensile properties of a near-& alpha; titanium alloy

Yu Zhou et al.

Summary: This study investigates the influence of equiaxed α content (a(e)) and configuration of α lamellas on the deformation mechanism and tensile properties of near-α titanium alloy. The bimodal microstructures (BMs) comprised of a(e) and parallel α lamellas (a colony) and basket-weave α lamellas (a basketweave) are denoted as BMC and BMB, respectively. With decreasing content of a(e), BMB shows higher strength and lower elongation reduction compared to BMC. Under the same content of a(e), BMB exhibits higher strength and better elongation than BMC. The deformation mechanisms of fully equiaxed microstructure (FEM), BMC, and BMB are investigated, revealing that prismatic slip is the dominant slip system and dislocation multiplication of prismatic slip dominates all a(e) grains. Basket-weave microstructure shows better slip transfer restraint and absence of continuous a(GB), leading to higher strength and better elongation.

Evolution and corrosion resistance of passive film with polarization potential on Ti-5Al-5Mo-5V-1Fe-1Cr alloy in simulated marine environments

Zhong Yang et al.

Summary: The evolution and corrosion resistance of the passive film on a Ti-5Al-5Mo-5V-1Fe-1Cr alloy were studied under different anodic polarization potentials in a 3.5 wt% NaCl solution. The valence state of Ti increased, while the corrosion resistance of the passive film exhibited a trend of weak to strong to weak as the polarization potential increased. Adsorption energy calculations revealed stable adsorption of Cl- on TiO2. The decrease in passive film corrosion resistance with increasing potential was attributed to the corrosion effect of corrosive ions on metal hydroxides.

Study of the passivation and repassivation behavior of pure titanium in 3.5 wt NaCl solution and 6 M HNO3 solution

Qiqian Chen et al.

Summary: This study reveals the differences in passive films composition and structure, as well as the repassivation rate of titanium in different solutions. Titanium exhibits worse corrosion resistance in 6 M HNO3 due to higher defect concentration, lower TiO2 content, and the accelerated dissolution/formation dynamic equilibrium of the passive film. In 3.5 wt% NaCl, the repassivation rate is higher despite the lower film growth rate.

Effect of Uniaxial Pre-strain on Tensile, Work Hardening, Fracture Toughness, and Fatigue Crack Growth Rate of Titanium Alloy Ti-6Al-4V

K. Saravanan et al.

Summary: This study investigated the effect of plastic deformation on the strength, work hardening behavior, fracture toughness, and fatigue crack growth rate of the Ti-6Al-4V alloy in annealed condition. It was found that increasing pre-strain led to a significant increase in ultimate tensile strength and yield strength, but a decrease in ductility. The presence of deformation texture at higher pre-strains resulted in an increase in deformation heterogeneity and altered the mechanism of crack initiation and propagation. The study also revealed that pre-strain significantly influenced the fracture toughness and fatigue crack growth rate of the alloy.

Comparative study on the crack growth behaviours of E690 steel and heat-affected zone microstructures under cathodic potential in artificial seawater based on mechano-electrochemical effect at crack tip

Yong Li et al.

Summary: The crack growth behaviors of E690 steel and HAZ microstructures under cathodic potential in artificial seawater were investigated and compared. The research found that the microstructural changes led to different crack growth paths. The crack growth rates first decreased and then increased at a certain cathodic potential, with the lowest rate occurring at -750 mV.

Annealed microstructure dependent corrosion behavior of Ti-6Al-3Nb-2Zr-1Mo alloy

Baoxian Su et al.

Summary: Annealing at higher temperatures increases the corrosion resistance of Ti80 alloy by forming a higher volume fraction of beta phase, which is more resistant to corrosion than alpha phase due to higher content of Nb, Mo, and Zr. However, severe corrosion is observed in 5 M HCl solution due to the breakdown of oxide films and micro-galvanic couple effects. These findings provide insights for designing Ti alloys with high corrosion resistance through microstructural optimization.

Effect of lamellar ? on the stress corrosion cracking of Ti-6Al-4 V alloy in simulated oilfield brine

Guangfang Chi et al.

Summary: The study investigated the stress corrosion cracking behavior of Ti-6Al-4 V alloy with different lamellar microstructures in simulated oilfield brine. It was found that the SCC susceptibility was lower in the Widmansta?tten sample compared to bimodal and trimodal samples, primarily due to the decrease in α/β colony size. The findings suggest that tailoring the lamellar α microstructure with different orientations and larger α colonies can help improve SCC resistance and crack growth resistance in oil field applications.

Rui Liu et al.

Summary: Hydrostatic pressure results in thinning and compositional changes of the passive film, accelerating its dissolution and reducing its protective effect on the alloy, especially when combined with tensile stress. The metal/film interface exhibits an undulating structure due to enhanced matrix dissolution cooperatively.

Cryogenic tensile properties and deformation behavior of a superhigh strength metastable beta titanium alloy Ti-15Mo-2Al

M. C. Zang et al.

Summary: The cryogenic tensile properties and deformation behavior of a metastable beta-Ti alloy Ti-15Mo-2Al were investigated, revealing superhigh ultimate tensile strength at 77 K and 20 K. The alloy shows high elongation-to-fracture at 77 K but drops sharply at 20 K, with enhanced work hardening rate and tensile strength at 77 K due to dynamic Hall-Patch effect. A serrated deformation occurs at 20 K, and cryogenic applications of the alloy are proposed to be feasible at temperatures not lower than 77 K.
