Iron Carbide, Fe3C (an important phase of steel also termed as cementite)

(metastable at all temperatures)

had no direct industrial application had certain amount of scientific

curiosity & challenge.

Preliminary experiments were done in Fritsch Pulverisette Mill available in

the institute that time (in 120 hr, very small Fe3C peak feasible) did not

.

Crude prototype was developed in 6 months and in 40 hr milled powderwas analyzed using XRay Diffraction: moment of triumph.
