    摘要:

    利用快速凝固法制備Ti12Zr10Si5Fe2Sn非晶合金條帶，采用XRD、TEM、SEM及拉伸試驗機等手段研究其組織結構和力學性能。結果顯示：該非晶鈦合金力學性能優(yōu)良，其抗拉強度高達399 MPa，屈服應力為329 MPa，斷裂延伸率為2.5%，彈性模量為39 GPa，較晶態(tài)金屬更接近于人體骨的彈性模量，另外對其斷口形貌進行觀察分析。

    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.
