Table 2

Ratios of the pearlite area, the graphite particles area, and the ferrite area.

Specimen no.	𝑃𝑟	𝐺𝑟	𝐹𝑟
	(1)	(2)	(3)
1	0	0.21	0.79
2	0.08	0.19	0.77
3	0.29	0.20	0.65
4	0.57	0.18	0.54

The ratios of the pearlite area, 𝑃_𝑟, the graphite particles area, 𝐺_𝑟, and the ferrite area, 𝐹_𝑟, are defined by (1), (2), and (3), respectively.
