Investigate not only the effect of temperature (which widens or narrows the molecular space allowing for more or less permeation of the steel) but also consider more important sympathetic vibrations which stratify or align molecular order while widening molecular expance then adjust vibration of the introduced element to phaze between the vibrating sympathetic steel. One should "hear" a "mathematical" purity to the steel as it is permeated if one obtains sympathetic vibration. Immediately upon "hearing" the induction of the magnetic presence into the steel reverse the temperature signifigantly to close the molecular distance and thus "harden" the steel. you will be able to lazer the surface of the steel and see the stratifications. Lazing in an induced field presence will create an interresting anamoly. Also try using bizmuth as a separation agent, you will be surprised how defined the stratifications are and how intense the magnetic "ripples" are.
