航空航天级钒铝中间合金的国内研究现状

Research Status of Aerospace Grade Vanadium Aluminum Intermediate Alloy in China

钒铝中间合金是生产高性能钛合金的重要中间合金,添加钒铝合金的钛合金具有较高的比强度、优异的耐腐蚀性和抗疲劳性能等.目前我国航空航天级钒铝中间合金制备技术尚不成熟,产品中的合金偏析、杂质含量高仍是规模化生产的关键瓶颈,仍未得到有效解决.本文总结了国内众多的航空航天级钒铝中间合金制备方法研究及现状,从生产工艺、环境和产品质量等方面进行客观的分析,提出了航空航天级钒铝中间合金产业化新技术的研究重点和方向.

Vanadium aluminum alloy is an important additive in the production of high performance titanium alloy.Al-V alloy is added to titanium alloy,which gives the titanium alloy a set of excellent properties such as high specific strength,excellent corrosion resistance and fatigue resistance,etc.However,the preparation technology of aerospace grade Al-V intermediate alloy is not mature in our country,and the alloy segregation and high impurity content in the product are still the key bottlenecks of large-scale production,which have not been effectively solved at present.This paper summarizes the research and status of many preparation methods in China,and analyzes objectively from the aspects of production process,environment and product quality,and the emphasis and direction of research on new technology of aerospace grade Al-V intermediate alloy industrialization are put forward.
