Effect of UV irradiation on the surface Gibbs energy of Ti6Al4V and thermally oxidized Ti6Al4V

Journal of Colloid and Interface Science, 2008
Thermal oxidation of Ti6Al4V increases the thickness, modifies the structure, and changes the amount of alloying elements of the surface titanium dioxide layer with respect to the spontaneous passive layer of Ti6Al4V. The effects on the surface properties of Ti6Al4V and thermally oxidized Ti6Al4V after different periods of UV irradiation have been ...

Functional bimetallic joints of Ti6Al4V to SS410 [PDF]

Additive Manufacturing, 2020
Bimetallic structures provide a unique solution to achieve site-specific functionalities and enhanced-property capabilities in engineering structures but suffer from bonding compatibility issues. Materials such as titanium alloy (Ti6Al4V) and stainless steel (SS410) have distinct attractive properties but are impossible to reliably weld together using ...

Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

Advanced Engineering Materials, EarlyView.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Influencia del arenado de la aleación Ti6Al4V en la dureza subsuperficial y estado de tensiones residuales

Revista de Metalurgia, 2009
El arenado de la aleación Ti6Al4V es un tratamiento orientado a la mejora de la fijación mecánica de los implantes. Sin embargo, dicho tratamiento contribuye a una disminución de la resistencia a la fatiga del material. En este trabajo se ha determinado,

Dynamic shear localization in Ti6Al4V

Procedia Engineering, 2011
AbstractThe alloy Ti6Al4V is known to be prone to the formation of adiabatic shear bands when dynamically loaded in shear. This causes a catastrophic decrease of the load carrying capacity and is usually followed by fracture. Although, the main mechanism is recognized to be the competition between strain hardening and thermal softening, a detailed ...

Mechanical Properties of Architected Polymer Lattice Materials: A Comparative Study of Additive Manufacturing and CAD Using FEM and µ‐CT

Advanced Functional Materials, EarlyView.
This study examines how pore shape and manufacturing‐induced deviations affect the mechanical properties of 3D‐printed lattice materials with constant porosity. Combining µ‐CT analysis, FEM, and compression testing, the authors show that structural imperfections reduce stiffness and strength, while bulk material inhomogeneities probably enhance ...
