The effect of corrosion-mud treatment on fatigue accumulated properties using 7049 al-alloy

الملخص EN

The present work deal with the effect of corrosion-mud on constant fatigue and accumulated using 7049 aluminum alloy.

Experimental results observed that fatigue life and strength strongly effect by corrosion-mud treatment.

The (fatigue life reduction factor percentage) FLRF% can empirically expressed by the equation FLRF% = 0.004688 * af + 3.0372 The fatigue strength was reduced to 10% due to mud corrosion fatigue interaction.

It was indicated that Miner rule underestimated the mud corrosion fatigue life interaction.
