我国航空用变形钛合金材料

钛合金材料作为一种20世纪中叶出现并发展起来的新兴结构材料,因其具有优异的耐腐蚀性、高的比强度以及无磁性等一系列独特的优点,在航空航天等高端工业部门获得了广泛应用,目前飞机机体结构中的隔框、大梁、起落架以及航空发动机压气机匣、轮盘、叶片等承力部件大量使用钛合金材料制造。在上世纪60年代,美国、英国、前苏联等工业发达国家就已经在飞机及航空发动机制造中大量使用钛合金材料。我国钛合金材料在航空工业中的应用起步较晚,上世纪80年代开始才陆续在飞机及航空发动机制造中少量使用钛合金材料,但是进入21世纪之后,我国航空工业钛合金材料的应用水平大幅度提升。对我国目前已经进入工业化生产并在航空工业中获得工程化应用的变形钛合金材料进行了系统阐述。

Deformation of Titanium Alloy Materials for China Aircraft

Titanium alloy appears as a mid-twentieth century,and developed new structural materials,because of its excellent corrosion resistance,high specific strength and non-magnetic and a series of unique advantages,such as high-end in the aerospace industry access to a wide range of applications,the current structure of the airframe bulkheads,beams,landing gear and the aircraft engine compressor tray,roulette,blades and other parts of extensive use of titanium bearing materials.60s in the last century,the United States,Britain,the former Soviet Union and other industrialized countries has been in the manufacture of aircraft and aero-engine heavy use of titanium material.Titanium alloy material of the application in the aviation industry started late 80’s until the last century,one after another in the manufacture of aircraft and aircraft engines use a small amount of titanium alloy materials,but the 21st century,China’s aviation industry application level of a large titanium alloy Rate increase,this article in China has entered the industrial production of and access to engineering applications in the aviation industry formulation of deformation of titanium alloy materials.
