      The contact fatigue behavior of three microstructurally distinct tool steels coated with a physical vapor deposited TiN film is studied. Substrate microstructural differences come from variations in either chemical composition ...

    • Tool steel selection for cold forming of high strength steels based on the stress distribution in tools 

      Hernández Rossi, Ricardo; Riera Colom, María Dolores; Casellas Padró, Daniel; Valls, Isaac; Casas Aguirregomezcorta, Begoña; Prado Pozuelo, José Manuel (Greyden Press, 2007)
