Nucleation mechanism of nano-sized NaZn13-type and α-(Fe,Si) phases in La-Fe-Si alloys during rapid solidification

Table 2 The chemical compositions determined by EDS for regions A and B of the melt-spun La-Fe-Si ribbon (Figure 2 ) relative to its nominal composition

Region	La (at.%)	Fe (at.%)	Si (at.%)
A	8.80	79.45	11.53
B	8.29	85.05	6.67
Nominal composition	8.35	81.2	10.82

Note that we added a 5% burning loss in La element because it was easy to volatile during the melting process of La-Fe-Si.
