STRUCTURAL PECULIARITIES OF AlTi-Zr MODIFYING LIGATURES

The opportunity of the complex aluminides Al3 (ZrxTi1-x) formation with metastable cubic L12 lattice is demonstrated. The intermetallides mentioned were forming during the Al-Ti-Zr melt crystallization. Since the meta-stable L12 structure is similar to the cubic fcc lattice of -Al, the application of such an alloys for aluminum alloys modifying is very perspective.
