no phase transformations were observed
between 1000 C and the onset of melting in the thermograms,
nor was there any evidence of phase evolution between Figs. 1 and
2, beyond the elimination of solidification induced microsegregation.
Therefore, it can be concluded that the two phases
formed during solidification are thermodynamically stable above
1000 C. This conclusion is in agreement with the predictions of
Tong et al. [3] and in contrast to the results of Ng et al
