The electrochemical corrosion behavior of the high entropy alloys was basically the same, the corrosion mainly occurred at the grain boundary due to interdendritic segregation. The corrosion degree of the three high entropy alloys was different from each other, which corresponds to different corrosion properties. A small number of corrosion particles were attached to the surface of TiZrTaNbMo alloy, and no obvious corrosion was observed, denoting excellent corrosion resistance as shown in Figure 4b. Severe corrosion occured on the surface of TiZrTaNbSn alloy, and there was a large number of corrosion pits and cracks on the surface as shown in Figure 4c.

The attraction between Ti and Sn atomic pairs is larger than the repulsion, as the heat of mixing of Ti and Sn is −21 kJ mol−1 , so the cluster containing the Ti–Sn atomic pair is easy to form. The mutual repulsion force between Fe and Sn is larger than the mutual attraction because of the positive heat of mixing of Sn and Fe, which leads to the decrease of Fe content in the Sn-rich region. Therefore, TiFe phases in Fe-rich regions and Ti phases in Sn-rich regions are formed in different regions. Although Ti content higher, the Sn content is less, so the Ti3Sn phase is difficult to form. The atomic ratio of Ti to Fe is located in hypoeutectic region, and the high Fe content results in the deposition of TiFe phase along the grain boundary of Ti phase.
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 .

As a result, the difference of content of TiFe phase between the two alloys is small, which is consistent with the small difference of volume fraction calculated by XRD in Table 1. With a further increase in Mo content and a further decrease in Fe content, for the Ti75Fe15Sn5Mo5 alloy, only two particles of TiFe phase labeled with the black arrow in Figure 2e,f can be observed. Its content is obviously smaller than that of TiFe phase in Figure 2b,e, which is also consistent with the small volume fraction of the TiFe phase that was calculated by XRD in Table 1.

Values of the three alloys are larger than that of the Ti75Fe20Sn5 alloy (5.00 GPa), which indicates that the addition of Mo element improves the hardness of the Ti75Fe20Sn5 alloys.

As the differences of diffraction angle for the strongest diffraction peak between the β-Ti and α-Ti phases are small, Figure 1b is a local magnification diagram of Figure 1a, to distinguish the diffraction peaks of the two phases. In fact, this result is consistent with the type of matrix phase and the second phase of Ti75Fe20Sn5 alloy , which suggests that the addition of minor Mo does not change the type of phase. Accordingly, that the addition of Mo changes the matrix phase and the second phase of Ti75Fe20Sn5 alloy. Thus, the matrix phase of the Ti75Fe19Sn5Mo1 and Ti75Fe15Sn5Mo5 alloys is the α-Ti phase, the second phases are the β-Ti and TiFe phases, while the matrix phase of Ti75Fe17Sn5Mo5 alloy is the β-Ti phase, and the second phases are the α-Ti and TiFe phases. The surface morphology of the high entropy alloys after electrochemical corrosion is shown in Figure 4. The surface was etched after electrochemical corrosion for 60 min.

T value of Ti75Fe19Sn5Mo1 alloy (57.8%) is larger than those of Ti75Fe17Sn5Mo3 (40.5%) and Ti75Fe15Sn5Mo5 (32.5%) alloys, which indicates that the Ti75Fe19Sn5Mo1 alloy has good intrinsic plasticity.

In addition, the more the Mo content is, the less the TiFe phase intermetallic compounds precipitate. This is consistent with the volume fraction that was calculated by XRD. The volume fraction of TiFe phase decreases with the increase of Mo content. The high Fe content results in deposition along the grain boundary of Ti phase.

The TiZrTaNiMo alloy shows excellent corrosion property according to the corrosion parameters Icorr, φcorr, Ipass. The corrosion property of the TiZrTaNb alloy deteriorated after the addition of Sn element and this is attributed to the interdendritic segregation of Sn element. The Ta, Mo elements are mainly enriched in dendrite and Zr, Ti, Nb, Sn elements are mainly distributed in the interdendritic in high entropy alloys, which is attributed to the different equilibrium distribution coefficients.
