Abstract

The nucleation behavior of the 1/1 quasicrystal approximant phase was investigated in Ti-TM-Si-O (TM=Mn, Cr, Fe) alloys made near the stoichiometric composition. Containerless solidification studies were performed using electromagnetic (rf) levitation and drop-tube techniques. The solidification microstructures indicate that α-Ti nucleated first in Ti-Cr-Si-O and β-Ti in Ti-Mn-Si-O alloys; the 1/1 phase nucleated and grew on these titanium oxide dendrites. In Ti-Fe-Si-O alloys, the 1/1 phase nucleated and grew directly from the liquid, allowing information on the nucleation rates to be obtained from undercooling data.
