ROTATING BEAM FATIGUE AND CORROSION FATIGUE PROPERTIES OF ALUMINUM AND MAGNESIUM ALLOYS,
Abstract
The S-N curves indicate that the materials in order of decreasing fatigue resistance at all stress levels are: 2014-T6, 2024-T4, 5086-H34, 5052-H34, 5052-H32, and AZ 31B. The fatigue resistance of the heat treated aluminum alloys, 2014-T6 and 2024-T4, is much superior to the fatigue resistance of the strain hardened alloys, 5086-H34, 5052-H34, and 5052-H32.... The S-N curves for the corrosion fatigugue tests indicate that the materials in order of decreasing corrosion fatigue resistance at stresses up to 150 percent of their endurance limits are: 5086-H34, 5052-H34, 2024-T4, 2014-T6, 5052-H32, and AZ 31B. In this stress range, 5086-H34 aluminum is much superior to the other materials. At stresses above 150 percent of their endurance limits, the materials in order of decreasing corrosion fatigue resistance are: 2014T6, 2024T4, 5086-H34, 5052-H34, 5052-H32, and AZ 31B. The corrosion fatigue resistance of AZ 31B was very poor at all stresses. (Author)
