EDX results of the four samples in Figure 3.

Positions	Nb (at %)	Si (at %)	O (at %)
a-white	98.2	1.6	0.2
a-grey	62.1	37.6	0.3
b-white	99.1	0.8	0.1
b-grey	62.6	37.4	—
c-white	98.7	1.1	0.2
c-grey	62.7	37.0	0.3
d	62.2	37.5	0.4

a-white, b-white, and c-white showed the concentrations of Nb, Si and O in the positions of white small particles in Figures 3(a), 3(b), and 3(c), respectively. Similarly, a-grey, b-grey, and c-grey showed the concentrations of Nb, Si and O in the positions of grey areas in Figures 3(a), 3(b), and 3(c), respectively. The concentrations of Nb, Si, and O in the sample Nb-37.5Si alloy in Figure 3(d) were shown in position d.
