Abstract
The invention relates to a method to process Interstitial-free (IF) steels by adapting multi-axial forging (MAF) at room temperature to provide increased strength and ductility by producing ultrafine grain structure within the steel, the method comprising the steps of providing a multi-axial forging apparatus having a base-plate, at least two die-panels, at least one plunger with a plurality of adapters; placing a course grain IF steel billet in between the at least two lubricated die-panels with a first axis of the billet along the axis of the plunger; pressing the billet with the at least one plunger along the first axis to reduce the length of the billet to half-the-original size with a corresponding increase in the smaller sides lying along a second axis; imparting a first rotation to the billet and repeating the steps (b) and (c) along a third axis; imparting a second rotation to the billet and repeating the steps (b) and (c) such that an elongation takes place along the first axis; and repeating the cycle comprising steps (b) to (e) till such time the grain size is reduced by at least three order of magnitude.
