“…In recent years, one of the key topics in the development of new metallic alloys is to develop the nano-/ultrafine-grained metallic materials with simultaneously improved strength and room temperature plasticity [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Among these metallic materials developed so far, Ti-based alloys are known as one of the potential lightweight engineering materials for industrial applications due to their excellent mechanical properties (yield strength w 1000 MPa and ductility w 10%) and good corrosion resistance [19].…”

“…In particular, enhanced mechanical properties have been obtained when the propagation of shear bands is limited in the area between the coarse primary dendrites embedded in the fine-scale eutectic matrix, preventing catastrophic failure [40e42]. Dislocations are generated inside the coarse primary dendrites and are piled up at the interface, thus promoting the plasticity and work hardening response [43,44].…”

TiFeCu alloys with higher Young's modulus, hardness and compressive mechanical properties than those of the existing Ti alloys were developed using a d-electrons alloy design method in order to improve Young's modulus, hardness and compressive properties of Ti and existing Ti alloys for use as metallic stents. Their microstructures, Young's modulus, hardness and compressive mechanical properties were investigated both before (as-cast) and after heat-treatments performed under a high-purity argon atmosphere at 1173 K for 21.6 and 86.4 ks.The studied TiFeCu alloys consist of the ¢-Ti phase and dendritic TiFe intermetallic phase. Moreover, the area fraction of the TiFe intermetallic phase increases with increasing atom ratio (Fe + Cu)/Ti of the alloys and with the heat-treatment time.The Young's modulus of the studied TiFeCu alloys increases from 110 GPa (Ti 78 Fe 18 Cu 4 alloy) to 145 GPa (Ti 68 Fe 30 Cu 2 alloy) with increasing atom ratio (Fe + Cu)/Ti of the alloys and the area fraction of the TiFe intermetallic phase. However, the Young's modulus is saturated or slightly decreased when the area fraction of the TiFe intermetallic phase is more than 34%. The Vickers hardness of the as-cast alloys increases from 490 HV (Ti 78 Fe 18 Cu 4 alloy) to 550 HV (Ti 63.4 Fe 30 Cu 6.6 alloy) with increasing atom ratio (Fe + Cu)/Ti of the alloys and area fraction of the TiFe intermetallic phase. On the other hand, the Vickers hardness of the heat-treated alloys is lower than that of the as-cast alloys, despite the increase in the area fraction of the TiFe intermetallic phase after the heat-treatment. The heat-treated alloys have better compressive properties than those of the as-cast alloys and the reported TiFeCu alloys. The compressive strength and strain of the heat-treated Ti 67 Fe 27 Cu 6 alloys reach to 2131 MPa and 24.5%, respectively.
