“…The expression of SLR and bulk forming ability (BFA) in amorphous state contributed to increase scientific interest and has a high potential of industrial application [2]. Recently, Ti-based amorphous alloys and Ti-based BMGs have been attempted to apply as bio-medical application by Ni-free Ti-based metallic glasses [3][4][5][6][7][8]. According to these results, Ni-, Al-and Be-free type Tibased BMGs indicate design criteria without these elements, increase of mechanical strength, decrease of elastic modulus as well as enhancement of corrosion resistance by amorphization and additional element effect.…”

The newly designed Ti-based bulk metallic glass (BMG) in which case of fracture behavior was observed 1990MPa to compressive strength with a wide plastic deformation around 7% after process of elastic deformation. This phenomenon can be compared with those of Ti-based alloys and other Ti-based BMGs and indicates high potential to be applied in use. It was evaluated the Ti-based BMG for thermal stability that the reduced glass parameters, ΔT x , T rg and γ, are 79K, 0.50 and 0.38, respectively. In addition, it reveals high activation energies for crystallization in which are estimated to E x1 = 291.77 ±9.71 kJ/mol, E x2 = 588.77 ±28.88 kJ/mol and E x3 = 330.26 ±3.61 kJ/mol on kissinger plotting in this study.

“…So far, a variety of Fe-based systems such as Fe-Mn, Fe-Pd and Fe-Mn-Si [1][2][3][4][5][6] has been or are being developed for the potential applications. The degradability of Fe-based DBMs can avoid various complications, such as chronic inflammation, thrombosis, in-stent restenosis [7,8] or even a second surgery to remove the implants [9,10], compared to the corrosion-resistant implants such as stainless steels 316L, Ti-based and Co-Cr-based alloys [11][12][13][14][15].…”

Fe-Mn-based degradable biomaterials (DBMs) are promising candidates for temporary implants such as cardiovascular stents and bone fixation devices. Identifying their mechanical properties and biocompatibility is essential to determine the feasibility of Fe-Mn-based alloys as DBMs. This study presents the tensile properties of two powder metallurgical processed Fe-Mn-based alloys (Fe-28Mn and Fe-28Mn-3Si, in mass percent) as a function of immersion time in simulated body fluid (SBF). In addition, short-term cytotoxicity testing was performed to evaluate the in vitro biocompatibility of the sintered Fe-Mn-based alloys. The results reveal that an increase in immersion duration deteriorated the tensile properties of both the binary and ternary alloys. The tensile properties of the immersed alloys were severely degraded after being soaked in SBF for ≥45 days. The ion concentration in SBF released from the Fe-28Mn-3Si samples was higher than their Fe-28Mn counterparts after 7 days immersion. The preliminary cytotoxicity testing based on the immersed SBF medium after 7 days immersion suggested that both the Fe-28Mn-3Si and Fe-28Mn alloys presented a good biocompatibility in Murine fibroblast cells.

With pure Ti and pure Zr as controls, the corrosion resistance, ion release behavior, and in vitro biocompatibility of Be-containing Zr₄₁Ti₁₄Cu₁₂Ni₁₀Be₂₃ bulk metallic glass (BMG) (LM1), Zr₄₄Ti₁₁Cu₁₀Ni₁₀Be₂₅ BMG (LM1b), and Be-free Zr₅₇Nb₅Cu₁₅.₄Ni₁₂.₆Al₁₀ BMG (LM106) were investigated in terms of electrochemical measurements in simulated body fluid (SBF) with pH value 7.4 and artificial saliva (AS) with pH value 6.3, and 3-[4,4-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay using L929 and NIH3T3 cells, aiming to assess the feasibility of Zr-based BMGs as potential biomaterial. It was found that LM1b showed superior corrosion resistance to LM106 and LM1 in both SBF and AS, and comparable with pure Ti and pure Zr. After 7200 s immersion, a two-layer structure oxide film was formed on LM1, LM1b, and pure Zr surfaces, while one-layer structure oxide film was formed on LM106 and pure Ti surfaces. The pitting corrosion potentials of LM1b were much higher than that of LM1, LM106, and pure Zr, resulting in very few ions releasing into the electrolytes. No Be ion could be detected but a little amount of Cu ion was detected for LM106, LM1, and LM1b after immersion in Dulbecco's modified Eagle's medium for 72 h at 37 °C. The indirect cytotoxicity results show that LM106, LM1, and LM1b extracts had no cytotoxicity to L929 and NIH3T3 cells. The direct cytotoxicity results show that cells could adhere well on the Zr-based BMG surface as in pure Ti and Zr. Lower cell proliferation rate of LM106 and LM1 is observed when compared with LM1b, which was found to be caused by Cu ion releasing rather than by Be ion.
