Microstructure and Mechanical Properties of Biomedical Ti-Zr-Nb-Ta-Sn High-Entropy Alloys

Metals, 2023
Ti(50-x)Zr38NbxTa8Sn4 high-entropy alloys with x = 0, 10, and 20 at.% were produced by vacuum arc melting in a high-purity argon atmosphere. The initial microstructures consisted of equiaxial bcc grains with sizes of 115 ± 30 µm, 250 ± 60 µm, and 280 ...

Overcoming the strength-ductility trade-off in refractory medium-entropy alloys via controlled B2 ordering

Materials Research Letters, 2022
Herein, we showed that controlled additions of Al, which provided a certain degree of B2 ordering, resulted in a ∼ 37%-enhancement of both yield strength and uniform elongation in Alx(NbTiZr)100-x (x = 0; 2.5; 5; 7.5 at.%) refractory medium-entropy ...

Deformation Behavior and Microstructure Evolution of a TiB-Reinforced Ti-6.5Al-2Zr-1Mo-1V Matrix Composite

Metals, 2023
A Ti-6.5Al-2Zr-1Mo-1V/TiB metal-matrix composite with 10.0 vol.% of TiB reinforcing fibers was produced using vacuum arc melting and compared with an unreinforced arc-melted Ti-6.5Al-2Zr-1Mo-1V alloy. The initial microstructure of the composite consisted

Oxidation Behaviour of Refractory (HfCo)_100−x(NbMo)_x High-Entropy Alloys with a bcc+B2 Structure

Applied Sciences, 2023
Herein, the oxidation behaviour of refractory (HfCo)100−x(NbMo)x (x = 0; 10; 25; 40; 75; 100 (at.%)) high-entropy alloys with a bcc+B2 structure subjected to cyclic oxidation at 1000 °C was studied. The single-phase B2-ordered HfCo alloy demonstrated the
