Al、Sn、Cu元素对钛合金力学性能及弹性模量的影响

Effect of Al, Sn and Cu on Mechanical Properties and Young's Modulus of Titanium Alloy

摘要: 研究了Al、Sn、Cu元素对钛合金强度、延伸率以及弹性模量的影响。结果表明,随着合金元素的增加,合金强度均升高;在试验范围内,Sn元素含量超过5%后,合金弹性模量和延伸率呈下降趋势,Al、Cu元素的增加对合金延伸率无明显影响,与弹性模量呈线性关系。

Abstract: The effect of Al,Sn and Cu elements on strength,elongation and young' modulus of titanium alloy is researched.The result indicates that the strength boosted with the increase of Al,Sn and Cu content in the range of this test,the young's modulus and elongation declined when the content of Sn exceed 5%,Al and Cu content has no obvious effect on elongation but increases the young's modulus.
