Modification Mechanism and Uniaxial Fatigue Performances of A356.2 Alloy Treated by Al-Sr-La Composite Refinement-Modification Agent
文献摘要：
Modification mechanism and uniaxial fatigue properties of A356.2 alloy treated by Al-6Sr-7La and traditional Al-5Ti-1B/Al-10Sr(hereinafter refers to traditional treated alloy)were investigated by constant stress amplitude method.Microstruc-ture,dislocation and Si twinning of the alloys were studied by thermal analysis,scanning electron microscopy(SEM)and transmission electron microscopy(TEM).The results showed that Al-6Sr-7La possesses better refining and modification effect than Al-5Ti-1B/Al-10Sr.Meanwhile,fatigue properties of the alloy treated by Al-6Sr-7La are higher than traditional treated alloy,and this is mainly owing to that Al-6Sr-7La treated alloy has more twins in eutectic Si and lower twin spacing.In addition,higher density of nanophases formed on twin faces and La-rich clusters appear at multiple twin intersections.Stacking faults and entrapped nanophases appeared on growing Si twin faces.Impurity induced twinning(ⅡT)mechanism and twin plane re-entrant edge(TPRE)mechanism are valid for eutectic Si which are important for mechanical optimization of A356.2 alloy.
