Glassy Pig Iron Material And A Process Thereof
Abstract: The present disclosure relates to glassy pig iron or modified pig iron alloy having soft magnetic properties and a process of preparation thereof. Said preparation process employs melt spinning technique comprising distinct parameters/features to obtain rapidly solidified glassy and amorphous pig iron or modified pig iron alloy with soft magnetic properties. The products are prepared in the form of ribbons, flakes or pulverized powders and are useful in applications including transformer application, magnetic powder cores, coating for electro-magnetic shielding, anti-corrosive coatings or any other application(s) requiring pig iron or corresponding alloys.
