Study on The Status and Development Trend of Fatigue Properties for Welded Joints of Mg-alloy

摘要

Magnesium alloy is a green engineering material in the 21st century,the study on magnesium alloy has attracted attention at home and abroad.Authors summarizes the latest study results and progress on fatigue properties of welded joint of magnesium alloys and their status at home and abroad in recent years.Problems and deficiencies were pointed out existing in the field of fatigue research about welded joint of magnesium alloy.Finally,the direction and focus to the study on fatigue properties and fatigue life of welded joints of magnesium alloys were analyzed.
