Creation of 3D Model of Stainless-Steel Billet's Grain after Three-High Screw Rolling.

The three-high screw rolling of AISI 321 billet from 60 mm to 52 mm diameter was performed using an MISIS-100T mill. When screw rolling was carried out, a set of sections were made in the billet's cross-section at the stationary stage of screw rolling. SolidWorks was applied to make the 3D model of the rolled billet's grain using microstructure images.
