Abstract:Ti12Zr10Si5Fe2Sn amorphous alloy was prepared by rapid solidification. Its microstructure and mechanical properties were investigated by XRD, TEM, SEM and a tensile testing machine. The results show that the Ti12Zr10Si5Fe2Sn amorphous alloy has good mechanical properties. Its tensile strength is up to 399 MPa, yield stress is 329 MPa, and elongation at break is 2.5%. Moreover, its elastic modulus is 39 GPa, which is closer to elastic modulus of human bone than that of crystal metal. In addition, the fracture morphology was also analyzed.
