On the formability of sheet steels
Bulletin of Materials Science, 1996 Formability of sheet steel in stamping operation primarily depends on strain hardening exponent (n), average plastic strain ratio (\(\bar r\)) and the maximum strain the material can undergo before the onset of localized necking. The formability parameters (n and\(\bar r\)) and the forming limit diagrams have been evaluated for a variety of sheet steel

Modelling of aluminium sheet forming at elevated temperatures [PDF]
, 2004 The formability of Al–Mg sheet can be improved considerably, by increasing the temperature. By heating the\ud sheet in areas with large shear strains, but cooling it on places where the risk of necking is high, the limiting drawing ratio\ud can be ...

Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution
Advanced Engineering Materials, EarlyView.Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability
