Effect of Alloying Composition on the Mechanical Properties of Ti 811 Alloy Rods

摘要:

研究了合金成分Ａｌ、Ｍｏ、Ｖ含量变化对Ｔｉ８１１（Ｔｉ－８Ａｌ－１Ｍｏ一１Ｖ）合金棒材性能的影响。结果表明：Ｔｉ８１１合金的性能受合金成分的支配。随合金成分Ａｌ、Ｍｏ、Ｖ含量的变化，Ｔｉ８１１合金的室温拉伸性能、高温拉伸性能、热稳定性能、冲击韧性、蠕变性能和缺口持久性能均有明显的升高或降低。同时应用ＴＥＭ和ＳＥＭ等技术研究了相应微观结构的变化。

Abstract:

he influence of alloying composition on the mechanical properties of Ti811 alloy rods was studied.The results show that the mechanical properties of Ti811 alloy are subject to alloying. composition.These properties include tensile properties at room temperature and high temperature,thermal stability, impact elasticity, creep properties and netched lasting properties.The variety of microstructures was investigated with the help of TEM and SEM techniques.
