Abstract

The development of prosthesis implantation as a means to treat bone defects in the field of orthopedic surgery is booming. Some materials with excellent biocompatibility are available for practical application, while new materials are being continuously developed. Gum metal is a new type of multifunctional β-type titanium alloy, and its basic composition can be expressed as Ti-24(Ta + Nb + V)-(Zr, Hf)-O. Gum metal has a good combination of a low elastic modulus and high strength, which promotes its emergence in the biological field. Moreover, gum metal combines the advantages of nonlinear elasticity, low work hardening rate and nontoxicity, making it a new material with potential in the future. This review begins with the design origin of gum metal and the influence of various elements on this kind of alloy. Second, the fabrication process and deformation mechanism of gum metal are summarized. Finally, the properties and current application fields of gum metal are introduced.

摘要

假体植入作为治疗骨缺损的一种手段在骨科领域的发展正在蓬勃发展。一些具有优良生物相容性的材料已经可供实际应用，同时新材料也在不断开发中。胶金属是一种新型多功能β型钛合金，其基本成分可表示为Ti-24(Ta+Nb+V)-(Zr,Hf)-O。胶金属具有低弹性模量和高强度的良好结合，促进了它在生物领域的兴起。而且，胶金属结合了非线性弹性、低加工硬化率和无毒等优点，使其成为未来具有潜力的新材料。这篇综述从胶金属的设计起源和各种元素对这种合金的影响说起。第二，总结了金属胶的制作工艺和变形机理。最后介绍了胶金属的性能和目前的应用领域。
