How many atoms are in one unit cell of ferrite (BCC)?

Hi please i want to know for one unit structure cubic ferrite we have 1/8*8+1 atome its mean 2 atome so my question is we have 1 atome F and 1 atome Carbon in middle for one unit crystal please someone explain

 

[EdStainless]

8 * 1/8 + 1 = 2 Fe atoms
The carbon is interstitial, in between the Fe atoms.

Kindly How many carbon atoms typically occupy interstitial sites per BCC iron unit cell in low-carbon steel?”

Isn't it just the percentage by weight of carbon?

 

[EdStainless]

Yes IR, it is very different for 1012 vs 1095.
Remember that an alloy that is 1wt% C is nearly 5at% C.

Was too lazy to do the math
