Special Issue Information

Dear Colleagues,

Titanium and its alloys are widely used engineering materials within the Aerospace, Automotive, Energy and Chemical industries. Their unique combinations of high strength-to-weight ratio, strong resistance to creep, excellent corrosion resistance, and low heat conductivity make them suitable for a wide range of applications. A large variety of microstructures, including lamellar, martensite, equiaxed globular and bimodal (duplex) microstructures can be obtained in titanium alloys depending on the thermomechanical processing routes. Despite a large amount of work in the field of investigation of microstructure evolution and mechanical properties of titanium alloys, detailed studies of the effect of their microstructure on the mechanical behavior are still necessary because of ever-increasing demands for structural materials to optimize their properties for different applications by varying processing parameters and resulting microstructures.

This Special Issue is focused on various aspects of microstructure evolution in titanium alloy samples obtained using traditional and additive technologies and subjected to different processing techniques as well as on the relation between their microstructure and mechanical behavior. Reviews and original articles in the areas of preparation and experimental characterization of titanium alloys as well as computer simulation of their mechanical behavior under different loading conditions are welcomed.

The microstructure and mechanical properties of a newly developed Fe-microalloyed Ti–6Al–4V titanium alloy were investigated after different heat treatments. The volume fraction and the morphological features of the lamellar α phase had significant effects on the alloy’s mechanical performance. A dataset showing the relationship between microstructural features and tensile strength, elongation, and fracture toughness was developed. A high aging temperature resulted in high plasticity and fracture toughness, but relatively low strength. The high strength favored the fine α and the slender β. The high aspect ratio of lamellar α led to high strength but low fracture toughness. The alloy with ~84 vol % α exhibited the highest strength and lowest fracture toughness because the area of its α/β-phase interface was the highest. Optimal comprehensive mechanical performance and heat-treatment procedures were thus obtained from the dataset. Optimal tensile strength, yield strength, elongation, and fracture toughness were 999 and 919 MPa, 10.4%, and 94.4 MPa·m1/2, respectively. Full article
