High-strength titanium alloys for aerospace engineering applications: A review on melting-forging process

Qinyang Zhao et al.

Summary: High-strength titanium alloys (HS-TAs) are crucial structural materials for advanced engineering applications. Achieving the synergy of high strength, high ductility, and high toughness has been identified as a technical bottleneck. Two primary strategies, developing novel alloys and innovating processing technologies, have been initiated to overcome this challenge. This review provides an overview of the research status, processing and heat treatment technologies, phase transformation, processing-microstructure-property correlation, and strengthening-toughening mechanism of HS-TAs for aerospace engineering applications.

Adsorption and diffusion behavior of hydrogen on the M-doped (M=Zr, Mo, Y, Cu, Pd, Ir, Mg, Al, Si) Ti(0001) surfaces: A first-principles study

Chunlei Shen et al.

Summary: The adsorption and diffusion behaviors of hydrogen on M-doped Ti(0001) surfaces were studied using first-principles calculations. The results show that different M dopants affect the surface energy and the adsorption position of hydrogen, as well as the diffusion path of hydrogen on the surface. These findings are important for understanding the effect of M doping on the surface properties of Ti and the behavior of hydrogen on Ti surfaces.

Optimization of processing parameters to produce nearly dense fine-grained Ti-6Al-4V microstructures with a hydrogen-assisted BEPM approach

Baicheng Wang et al.

Summary: In this study, a fine-grained and nearly dense Ti-6Al-4V alloy was successfully produced using press-and-sinter blended elemental powder metallurgy method. The developed methods, including thermocycling and hydrogenation-dehydrogenation, allowed for desirable alloy microstructure at a relatively low sintering temperature. The resulting alloy exhibited fine grain size, acceptable oxygen content, reduced residual porosity, and suitable tensile characteristics for practical application.

Revealing dehydrogenation effect and resultant densification mechanism during pressureless sintering of TiH2 powder

T. Chen et al.

Summary: The use of TiH2 powder as a sintering precursor shows potential for producing nearly full-density titanium and titanium alloys with superior mechanical properties. The study reveals a two-step sintering strategy that demonstrates the dehydrogenation effect and densification mechanism of TiH2 powder during pressureless sintering. Results indicate that TiH2 powder exhibits significant advantages over HDH-Ti powder in terms of densification rate, grain size, strength, and ductility.
