现代飞机需要这样一种铝合金:它既具有7075-T6状态的机械性能,同时又具有轻度过时效T7状态的改进的抗蚀性能。IN-9052和IN-9021是两种新的铝合金,在抗拉强度、疲劳强度、韧性和抗蚀性能等综合性能方面是十分引人注目的。 IN-9052(4.0％Mg,0.8％O,1.1％C)在成份上与5083合金相近,并也和后者一样不
Modern aircraft require an aluminum alloy that has both the mechanical properties of the 7075-T6 state and the improved corrosion resistance of the light over-aged T7 state. The IN-9052 and IN-9021 are two new aluminum alloys that are compelling in terms of overall performance such as tensile strength, fatigue strength, toughness and corrosion resistance. IN-9052 (4.0% Mg, 0.8% O, 1.1% C) is similar in composition to the 5083 alloy and is the same as the latter
