Abiadura handiko entseguak egiteko forjaketa-mailu baten garapena
Agirre, Julen; Otegi, Nagore; GALDOS, Lander; Arrese Irazabal, Peio (UEU, 2021)Hammer forging is a widely employed manufacturing process to produce parts with excellent mechanical properties. In order to achieve an optimal process design, finite element modelling is broadly utilized in industry and ... -
Characterization of Ti64 forging friction factor using ceramic coatings and different contact conditions
GALDOS, Lander; Mendiguren, Joseba; Sáenz de Argandoña, Eneko; Agirre, Julen (Elsevier, 2017)Hot forging processes are highly influenced by the contact conditions between the billet and the dies. A wrong definition of the contact conditions may lead to wrong predictions of the final component geometry, the quantity ... -
Design of a new simulative tribotest for warm forming applications having high contact pressure and surface enlargement
GALDOS, Lander; Agirre, Julen; Aranburu Eziolaza, Elixabet (Materials Research Forum LLC., 2023)Many tribological tests have been developed in the last decades to emulate real cold forging processes at laboratory conditions and to obtain friction coefficients at different process conditions. In this paper a new ... -
Effect of near beta-transus forging parameters on the mechanical and microstructural properties of Ti-6Al-4V: Application to hammer forging
Agirre, Julen; Erice, Borja; Arrese Irazabal, Peio; GALDOS, Lander (Materials Research Forum LLC., 2023)Ti-6Al-4V is a widely employed material in the aerospace, power generation and bioengineering industries due to its low density, excellent corrosion resistance and outstanding mechanical properties. Hammer forging is one ... -
High-Speed Material Characterization Using an Instrumented Forging Hammer
Agirre, Julen; Abedul Moreno, David; Oruna Otalora, Angel; GALDOS, Lander (Springer, 2021)Hammer forging is a widely employed manufacturing process to produce parts with excellent mechanical properties. Although the rheological behavior and the microstructural transformation phenomena of metals under hammer ... -
Hole expansion test of third generation steels
Agirre, Julen; Mendiguren, Joseba; GALDOS, Lander; Sáenz de Argandoña, Eneko (AIP Publishing, 2017)The trend towards the implementation of new materials in the chassis of the automobiles is considerably making more complex the manufacturing of the components that built it up. In this scenario materials with higher ... -
Simulation of Cold Forging Processes Using a Mixed Isotropic-Kinematik Hardening Model
GALDOS, Lander; Agirre, Julen; Otegi, Nagore; Mendiguren, Joseba; Sáenz de Argandoña, Eneko (Springer, 2021)Cold forging is a manufacturing process where a bar stock is inserted into a die and squeezed with a second closed die. It is one of the most widely used chipless forming processes, often requiring no machining or additional ...
