and determined. The results show that the deposited aluminum-magnesium alloy coating is smooth, uniform and compact. The component of magnesium exists in the coating with Al-Mg solid solution and forms... that of pure aluminum coating under the same electro-deposited condition. The optimum current density for Al-Mg alloy coatings in organic solvent electrolyte is ranged from 0.75 to 1.50A/dm2. Key words......

And the lattice constant of Al phase in Al-17Zn-1.5Mg alloy changes little. Furthermore, Mg with larger atomic radius saturating in Al phase leads to the increment of the lattice constant in Al-Mg-Zn alloy......
. The strengthening of the micro-alloyed Al-Mg alloys is attributed to the precipitation strengthening by the Al3Sc particles and to the substructure strengthening. Key words: Al-Mg alloy; Al-Mg-Mn-Sc alloy...) and (d)), where it is the finest in alloy D. This suggests that addition of Mn or Sc could retard recrystallization of the Al-Mg alloys during hot-rolling, and the retarding effect is the best when Sc......
