Differences of grain-refining effect of Sc and Ti additions in aluminum by empirical electron theory analysis YE Yi-cong(叶益聪)1, HE Liang-ju(何良菊)2, LI Pei-jie(李培杰)1 1. National Center of Novel.... The empirical electron theory (EET) of solids and molecules was employed to calculate the valence electron structures (VES) of Al3Ti and Al3Sc. The conclusions can be drawn that, in the two alloys Al-Ti......
