摘要

对Ti-ANb-Ta

Ti-ANb-BTa-Zr系列合金进行了研究

探讨了固溶态下Ta、Zr对钛合金性能及组织的影响。在固溶态下

Ti-ANb-Ta

Ti-ANb-BTa-Zr合金均具有较低的弹性模量

达60GPa;具有优良的塑性性能

伸长率最高达32%

断面收缩率最高达80%;合金抗拉强度随Ta、Zr含量的增加

在500～700MPa之间变化

且呈上升趋势。合金固溶态显微组织主要是残余β+针状马氏体α″

随β稳定元素Ta和中性元素Zr增加

残余β增加

针状马氏体α″减少。

Abstract

Effects of Ta

Zr on properties and microstructure of solid solution Ti alloy were investigated by analyzing Ti-ANb-Ta

Ti-ANb-BTa-Zr series alloys. Solid solution Ti-ANb-Ta

Ti-ANb-BTa-Zr series alloys exhibit lower elastic modulus in which the lowest value is 58 GPa and excellent plastic performance in which maximum value of elongation and contraction of area reach 32% and 80%

respectively. With increasing in Ta and Zr contents

tensile strength of the alloys is increased in range of 500

00 MPa. Microstructure of the solid solution alloy is composed of residual β phase and acicular martensite α″

in which with increasing in Ta and Zr

residual β phase is increased with the decrease of acicular martensite α″.
