Contact Fatigue Behavior of PVD-Coated Steel
Ramírez, Giselle; Tarres, Elena; Casas Aguirregomezcorta, Begoña; Valls, Isaac; Martínez Martínez, María del Rosario; Llanes Pitarch, Luis Miguel (2009)
Article
Accés restringit per política de l'editorialIn this study, the contact fatigue behavior of a PVD TiN coating deposited onto DIN 1.2379 coldwork tool steel is assessed by cyclic spherical indentation. Experimental characterization focuses on the evaluation of ... -

Estudio de la resistencia a fatiga térmica en moldes de inyección de aluminio utilizando aceros de alta conductividad térmica
Molas, Sílvia; Hamasaiid, Anwar; Llobet, Albert; Valls, Isaac; Casellas Padró, Daniel; Riera Colom, María Dolores (2013)
Text en actes de congrés
Accés obertLa mayoría de los mecanismos de fallo que determinan la durabilidad de un molde de inyección de aluminio a alta presión están relacionados con las solicitaciones termo-mecánicas de la superficie. En cada ciclo, la ... -
Hard cutting of tailored hardened 22MnB5
Laumann, Till; Picas Anfruns, Ingrid; Grané, Marc; Casellas Padró, Daniel; Riera Colom, María Dolores; Valls, Isaac (Technischen Universität Graz, 2010)
Text en actes de congrés
Accés restringit per política de l'editorialIn the present work, the feasibility of creating low strength zones in flanges of tailored hardened 22MnB5 is evaluated by means of the combining high and low thermal conductivity tool materials. Finite Element (FE) ... -
Influence of substrate microstructure on the contact fatigue strength of coated cold-work tool steels
Llanes Pitarch, Luis Miguel; Ramirez, Giselle; Mestra Rodríguez, Álvaro Miguel; Casas, B.; Valls, Isaac; Martinez, R.; Bueno, R.; Goez, Alexey; Mateo García, Antonio Manuel (2012-02-25)
Article
Accés restringit per política de l'editorialThe 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)
Text en actes de congrés
Accés obertThe excellent combination of high mechanical strength, high elongation and strain hardening of Advanced High Strength Steels (AHSS) has allowed their increasing use in the automobile industry to reduce vehicle weight and ...
