摘要
研究了新型的7B04铝合金预拉伸厚板不同热处理状态的断裂韧性和疲劳裂纹扩展性能变化,试验结果表明,该合金T7451状态的断裂韧性和疲劳裂纹扩展性能明显优于T651状态的性能。
Variations in fracture toughness and fatigue crack-growth properties were studied through the prestretching plates of dif- ferent temper 7B04 new type aluminum alloys. The results show that the fracture toughness and fatigue crack-growth properties of T7451 temper have obvious superiority over that of T651 temper.
