- 摘要:
- 钛合金具有比强度高、热强度高、耐腐蚀性能和高温性能好等优点,成为航空航天飞行器的主要结构材料之一。随着航空发动机性能的提升,对钛合金的使用温度提出了更高的要求。到目前为止,世界上成熟使用的高温钛合金的最高使用温度为600℃,如美国的Ti1100合金,英国的IMI829、IMI834合金及俄罗斯的BT18Y、BT36合金等。重点介绍了国际上几种典型的高温钛合金的性能特点,以期为我国高温钛合金的研发和应用提供一些思路。Titanium alloy has the advantages of high specific strength,high hot strength,favorable corrosion resistance and high thermal strength,etc.,Which has become one of the main structure material of aircraft material.With the continuous progress of aeroengines,higher-working-temperature titanium alloys have been demanded.Recently,the highest temperature of mature using high temperature titanium alloy is 600℃.such as Ti1100(USA),IMI829(UK),IMI834(UK),BT18Y(Russia),BY36(Russia),etc.Then property features at 600℃for several typical high temperature titanium alloys were reviewed,and finally the key developing directions in the future are proposed.
