摘要：

The　fatigue　crack　propagation　and　the　crack　closure　behaviour　of　15Mn　mild　steel　in　3.5%　sodium　chloride　solution　are　studied.　An　equation　to　calculate　the　crack　closure　effect　induced　by　corrosion　products　is　proposed.　The　results　reveal　that　the　crack　closure　effect　has　a　remarkable　influence　on　corrosion　fatigue.　The　crack　closure　effect　decreases　and　disappears　with　crack　propagation.　The　effect　of　crack　closure　on　the　crack　growth　rate　and　on　the　corrosion　fatigue　mechanisms　is　discussed.　©　1991.
