Silicon Steel

If of steel the annealing temperature is $T_{boom}$ of the dopant $Fe_3C$ then other additives with their corresponding $T_{p}$ as annealing temperature may result in steel of varying desirable properties.

For example, silicon $Si$, as an additive.  $Fe_3Si$, $Z=3*26+14$, density $7220\,kgm^{-3}$, molar mass $195.6205 g\,mol^{-1}$,

$v_{boom}=3.4354*\cfrac{density}{Z}$

$v_{boom}=3.4354*\cfrac{7220}{3*26+14}=269.60\,ms^{-1}$

And,

$T_{boom}=v^2_{rms}*\cfrac{Molar\,mass}{3*8.3144}$

$T_{boom}=269.60^2*\cfrac{195.6205*10^{-3}}{3*8.3144}=570.03\,K$  or  $296.89\,^oC$

and also,

$T_{p}=v^2_{rms}*\cfrac{Molar\,mass}{2*8.3144}$

$T_{p}=269.60^2*\cfrac{195.6205*10^{-3}}{2*8.3144}=855.05\,K$  or  $581.90\,^oC$

If steel uses $Si$ as an additive, does heat treatment at $581.90\,^oC$ causes the material to strengthen as in annealing of steel?
