THE EFFECT OF CORROSION-MUD TREATMENT ON FATIGUE ACCUMULATED PROPERTIES USING 7049 AL-ALLOY

Abstract

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 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.
