铝合金在现代飞机上的应用研究

Application of aluminum alloy in modern aircraftABSTRACTWith the continuous development and progress of aircraft manufacturing technology andAeronautical Materials Science,it is believed that the selection of aluminum alloy in aircraftstructural materials can be replaced by titanium alloy and advanced composite materials.However,in recent years,with the continuous research on new materials,the research onaluminum alloy has also made great progress,and great potential of materials has been explored.Because of the price advantage and technological advantage of aluminum alloy compared withother alloys and composite materials,the structural materials of modern aircraft are mainlyaluminum alloy.Through the performance of aluminum alloy,welding process and surfacetreatment technology,aluminum alloy has been widely used By adjusting and studying the alloy,we can get the structural materials with excellent performance and suitable for modern aircraft.Modern aircraft need to use materials with light weight,good corrosion resistance and highstrength.This is the main reason why aluminum alloy is widely used in this industry,because itcan not only meet all these needs,but also the price is relatively low.It can bring economicbenefits beyond value in the industry.Key words:Modern aircraft aluminum alloy high strengthII
