Effect of carbon wt% on the iron x-ray diffraction pattern and the volume of iron unit cell.

Author
Abstract
From standard x-ray diffraction chart for iron noticed that the effect of increasing in carbon wt% are accompanied with the change in the volume of the iron unit cell, after diffusion of carbon atoms it takes interstitial position between irons atoms, this will increase the edge length of the unit cell by follow the relationship (Δ c =0.11285 ×C wt%), a permanent strain happens with the change in the mean of the lattice spacing.
This relation between carbon wt% and the volume of iron unit cell can be use to predict the carbon which is present in the iron alloy. The diffraction pattern act as an empirical fingerprint for carbon % and their phases.
