Formation of optical dark area (ODA) on high-cycle fatigue fracture surface of Al–Cu–Mg alloy at atmosphere induced by inner friction

Formation of optical dark area (ODA) on high-cycle fatigue fracture surface of Al–Cu–Mg alloy at atmosphere induced by inner friction

The formation of optical dark area (ODA) on high-cycle fatigue fracture surface of Al alloys at atmosphere is very common and questionable in the engineering fields. Herein, we discovered that the oxygen induced inner friction causes the serious Cu element segregation in the form of nanoparticles on...
