    • Simulación elastoplástica de los contactos entre partículas en materiales granulares 

      Riera Colom, María Dolores; Prado Pozuelo, José Manuel (2003)
      Conference report
      Open Access
      Los mecanismos que rigen la densificación de los materiales granulares durante su compactación son fuertemente dependientes de los estados de tensión y deformación en las zonas de contacto entre partículas. Un modelo ...
    • Simulation of the compaction process of a two-level powder metallurgical part 

      Bejarano, C; Riera Colom, María Dolores; Prado Pozuelo, José Manuel (Universidad Carlos III de Madrid (UC3M), 2001)
      Conference report
      Open Access
      In this work, a Plasticity model for granular materials, based on the Drucker-Prager/CAP model, is applied to represent the behaviour of the metallic powders during their cold die compaction. The elastic deformation has ...
    • TIG welding studies on sinter-forged low alloy steel 

      Riera Chavarria, Marcel (Universitat Politècnica de Catalunya / School of Mechanical Engineering, 2011)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      TIG welding is a very clean welding, and produces high-quality welds. But usually it’s performed manually, so that the quality of weld depends on the skill of the operator, and there’s not so much theoretical information ...
    • Ultrasonic inspection system for powder metallurgy parts 

      Turó Peroy, Antonio; Chávez Domínguez, Juan Antonio; García Hernández, Miguel J.; Bulkai, András; Tomek, Péter; Tóth, Gabor; Gironés, Ana; Salazar Soler, Jorge (2013-04)
      Article
      Restricted access - publisher's policy
      The demand for powder metallurgy (P/M) parts in its traditional automotive market is predicted to grow, but future sector expansion depends directly upon its capability to manufacture zero-defect parts for industries such ...
    • Wear damage mechanisms in 3Y-TZP ceramics 

      Hvizdos, Pavol; Mestra Rodríguez, Álvaro Miguel; Anglada Gomila, Marcos Juan (2008)
      Article
      Restricted access - publisher's policy
      Tribological behaviour of two 3Y-TZP materials (polycrystalline zirconia stabilized by 3% of yttria) with different heat treatments (i.e. different grain size) has been studied using ball-on-disc technique in dry conditions ...
