For a given composition of low alloy steel, is there any formula to find out how much fraction of an alloying element would end up in ferrite and how much in pearlite if one starts from austenite from austenite zone and then keep on continuous cooling at a given rate? Without using simulation, how would i find out distribution of typical alloying elements in cooling rate. Qualitatively, it is obvious that slower cooling rate would cause less supersaturation in ferrite phase, but semi-quantitatively, I want to know about any suitable formula that finds ferrite:pearlite alloying element distribution ratio as a function of cooling rate and alloy content. My prime alloying elements are C,P, S, (
