In Figure 2d, the continuous and discontinuous layers observed are the phenomenon of the complete and incomplete wetting of grain boundary. A large number of discontinuous layer of α-Ti phases show a structural of incomplete wetting, as shown in the letter C in Figure 2f. Accordingly, adding tge Mo element can change the complete and incomplete wetting of grain boundary. X-ray was used for phase analysis of the three high entropy alloys and the results are shown in Figure 1. Two kinds of BCC structures were identified and labeled BCC1 and BCC2. It can be seen that the position of the diffraction peak changed after the addition of Mo and Sn elements, but the crystal structure did not change, which was attributed to the lattice distortion.

For hypereutectic Ti–Fe alloys, the high content of brittle TiFe phase leads to the low ductility of the alloys. It is necessary to reduce the content of Fe to control the content of TiFe phase. Therefore, some researchers choose the Ti70.5Fe29.5 eutectic component as base alloy . When the minor Sn and Nb elements are added into eutectic Ti70.5Fe29.5 alloy, the grain size is refined and the content of TiFe phase is further reduced, which can improve the strength and ductility of the Ti–Fe-based alloys .

According to Figure 2a,b, the larger black particles at the boundary are TiFe phase, and TiFe phase deposits along the grain boundary. The point scanning of the regions labeled P4 and P5 at grain boundaries was carried out to better determine the enrichment of Fe elements at grain boundaries. The Ti and Fe contents at regions labeled P4 and P5 slightly differ. At the region labeled P5, Sn content is significantly lower than that at regions of grain boundary labeled P2, and also lower that that at the region of grain interior labeled P1. When the Sn-rich region appears at region labeled P1, the Sn-poor region will inevitably appear around it to reach the equilibrium state of Sn content for the whole alloy.

Five-point scanning shows that the Sn content is low when the Fe content is high. This is because the heat of mixing of Fe and Sn is positive. In the process of melt cooling, the repulsion force of Fe and Sn atoms is larger than the attraction force, which results in the diffusion of Fe and Sn atoms in the opposite direction.

A high entropy alloy is a new alloy proposed at the beginning of this century . It is a multiprincipal element alloy with five or more main elements and each element’s content is between 5% and 35%, which breaks the design concept of the traditional alloy and creates a new idea for alloy design . Previous studies have shown that the elastic modulus of a high-entropy alloy with BCC structure is low, which can achieve a better match with the human body and is more suitable for implantation materials . Todai et al. prepared a series of high-entropy alloys for use in bone repair (TiNbTaZrHf, TiNbTaZr, TiNbTaZrMo, etc.) by alloying safe elements without cytotoxicity and sensitization factors. The as-cast TiZrTaNb exhibited a single BCC phase and achieved a compressive yield strength of 1100 ± 90 MPa, strain of 48 ± 6%, and modulus of 116 ± 6 GPa .
The percentages of four elements of five spots are shown in the right border of Figure 3a. The region that is labeled P1 is the middle part of a complete grain. The composition of the grain is Ti79.35Fe10.16Sn8.25Mo2.24. The results show that the content of Fe in the grain is less, while the content of Fe increases near the grain boundary, and the contents of Sn and Mo correspondingly decrease at the grain boundary. When point scanning was carried out at grain boundary , the contents of Ti, Fe, Sn and Mo elements are 70.74 at.%, 26.47 at.%, 2.33 at.%, and 0.46 at.%, respectively. It is found that the contents of Ti, Sn, and Mo at the P2 region were significantly smaller than those at the P1 and P3 regions, while the contents of Fe at the P2 region are significantly larger than those at the P1 and P3 regions.
Accordingly, these results are consistent with the calculated data in Table 1. The microstructures of the eutectic Ti–Fe-based alloys are composed of β-Ti and TiFe phase . Although the content of TiFe phase for the eutectic Ti–Fe-based alloys is lower than that of TiFe phase for the hypereutectic Ti–Fe-based alloys, the content of TiFe phase for the former is still high, which affects the strength and ductility of the Ti–Fe-based alloy. Ternary Ti–Fe–Cu, Ti–Fe–Ta, and Ti–Fe–Co and quaternary Ti–Fe–Sn–Nb hypoeutectic alloys have been reported to further reduce the content of TiFe phase .

The movement of dislocation in the grain boundary is affected by the grain boundary, which results in the stress concentration caused at the grain boundary. When the concentration stress reaches the grain boundary strength, the crack at the grain boundary leads to the formation of dimples of intergranular fracture. Figure 2 shows the microstructure of the Ti–Fe–Sn–Mo alloys.
