      En el presente trabajo se ha realizado un estudio de la modificación de las propiedades mecánicas de la aleación de aluminio AA6060 F, al ser deformada mediante deformación plástica severa empleando el proceso de extrusión ...
    • Analysis of fatigue and wear behaviour in ultrafine grained connecting rods 

      Luri Irigoyen, Rodrigo Upna; Luis Pérez, Carmelo Upna; León Iriarte, Javier Upna; Fuertes Bonel, Juan Pablo Upna; Salcedo Pérez, Daniel Upna; Puertas Arbizu, Ignacio Upna (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      Over the last few years there has been an increasing interest in the study and development of processes that make it possible to obtain ultra-fine grained materials. Although there exists a large number of published works ...
    • Design and mechanical properties analysis of AA5083 ultrafine grained cams 

      Salcedo Pérez, Daniel Upna; Luis Pérez, Carmelo Upna; Luri Irigoyen, Rodrigo Upna; Puertas Arbizu, Ignacio Upna; León Iriarte, Javier Upna; Fuertes Bonel, Juan Pablo Upna (MDPI, 2017)   Artículo / Artikulua  OpenAccess
      This present research work deals with the development of ultrafine grained cams obtained from previously ECAP (Equal Channel Angular Pressing)-processed material and manufactured by isothermal forging. The design and the ...
    • Design, optimization, and mechanical property analysis of a submicrometric aluminium alloy connecting rod 

      Fuertes Bonel, Juan Pablo Upna; León Iriarte, Javier Upna; Luis Pérez, Carmelo Upna; Salcedo Pérez, Daniel Upna; Puertas Arbizu, Ignacio Upna; Luri Irigoyen, Rodrigo Upna (Hindawi, 2015)   Artículo / Artikulua  OpenAccess
      Ultrafine grained materials have a great deal of both scientific and technological interest because they allow outstanding properties to be obtained. An improvement in the mechanical strength and in the ductility and a ...
    • Design, simulation and manufacturing of a connecting rod from ultra-fine grained material and isothermal forging 

      Fuertes Bonel, Juan Pablo Upna; Luis Pérez, Carmelo Upna; Luri Irigoyen, Rodrigo Upna; Salcedo Pérez, Daniel Upna; León Iriarte, Javier Upna; Puertas Arbizu, Ignacio Upna (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      In this research work, a study on the mechanical properties of isothermal forging for connecting rods is made from previously ECAP (Equal Channel Angular Pressing)-processed AA1050 and AA5083 aluminium alloys. This severe ...
    • Experimental modelling of critical damage obtained in Al-Mg and Al-Mn alloys for both annealed state and previously deformed by ECAP 

      Luri Irigoyen, Rodrigo Upna; Fuertes Bonel, Juan Pablo Upna; Luis Pérez, Carmelo Upna; Salcedo Pérez, Daniel Upna; Puertas Arbizu, Ignacio Upna; León Iriarte, Javier Upna (Elsevier, 2016)   Artículo / Artikulua  OpenAccess
      Assessing the damage produced in plastic deformation processes permits the optimum manner to shape a material that could avoid any cracks from appearing. In this present research work, the absolute critical damage in ...
