Preparation and Mechanical Properties of Ti12Zr10Si5Fe2Sn Amorphous Alloys

摘要:

利用快速凝固法制备Ti12Zr10Si5Fe2Sn非晶合金条带，采用XRD、TEM、SEM及拉伸试验机等手段研究其组织结构和力学性能。结果显示：该非晶钛合金力学性能优良，其抗拉强度高达399 MPa，屈服应力为329 MPa，断裂延伸率为2.5%，弹性模量为39 GPa，较晶态金属更接近于人体骨的弹性模量，另外对其断口形貌进行观察分析。

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.
