Influence and Theory Analysis of Ti, Zr, B on the Refining Effect of Aluminum Alloy

Abstract:

The valence electron structures and bond energies of Al3Ti, Al3Zr, TiB2 and ZrB2 are studied based on the empirical electron theory of solids and molecules (EET theory), giving theoretical explanation on the different microstructure with different atomic number ratio of Ti, Zr and B in aluminum alloys. It is demonstrated that the formation of TiB2 and ZrB2 have priority for their bond energies are stronger than that of Al3Zr and Al3Ti. In addition, refining effect of Al3Ti and Al3Zr to Al is better.
