Fatigue Property of Welded Joints of Ti6Al4V Titanium Alloy in Corrosion Environment

The fatigue property of welded specimen of different form of Ti6Al4V Titanium Alloy plate was researched in the environmental condition of atmosphere and salt fog,The test results indicate the holes along weld seam in welding specimen have great influence on fatigue property, The fatigue life of Ti6Al4V Titanium Alloy doesn't low under the salt fog condition in high stress range. The salt fog brings about the influence on fatigue life obviously at the same corrosion condition with fatigue stress lowering.
