主 题:Mg alloys Suzuki segregation Stacking fault Frank partial dislocation
摘 要:Stacking faults(SFs)and the interaction between solute atoms and SFs in a Mg–Bi alloy are investigated using aberration-corrected scanning transmission electron *** is found that abundant I_(1)SFs are generated after cold rolling and are mainly distributed inside{1012}*** aging treatment,the formation of single-layer and three-layer Bi atom segregation in the vicinity of I_(1)fault are clearly *** segregation also occurs at the 1/6bounding Frank partial dislocation *** segregation behaviors in I_(1)fault and Frank dislocations are discussed and rationalized using first-principles calculations.
