      Turegano Marchan, Sergi (Universitat Politècnica de Catalunya, 2010-06-28)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      Covenantee:   Centre de Disseny d’Aliatges Lleugers i Tractaments de Superfícies
      La industria actual demanda la disminución de costes en los procesos productivos así como la obtención de componentes de formas complejas, ligeros y con buenas propiedades mecánicas. Las técnicas de conformado en estado ...
    • Preparation of Metal Nanoparticles via Sonochemical Reduction 

      Saura Puig, Oriol (Universitat Politècnica de Catalunya / Univerza Mariboru, 2011)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      Pure nickel, copper and zinc nanoparticles were prepared from chlorides of these elements using ultrasound with three different reducing agents (zinc, aluminum and magnesium). In the second part, syntheses of nickel-copper ...
    • Synthesis and characterization of Ni-Mn-Ga alloys with addition of Cu 

      Conesa Martin, Albert (Universitat Politècnica de Catalunya / Univerza Ljubljani, 2013)
      Master thesis (pre-Bologna period)
      Open Access
      Covenantee:   Univerza v Ljubljani
      Non-stoichiometric Heusler Ni-Mn-Ga based alloys with addition of up to 7,5 at.% of Cu were prepared. Homogenized alloys were characterized using polarized light microscopy, X-ray diffraction, differential scanning calorimetry ...
    • Texture development during hot deformation of an Al/Mg alloy reinforced with ceramic particles 

      Rezayat, Mohammad; Parsa, Mohammad Habibi; Mirzadeh, Hamed; Cabrera Marrero, José M. (2019-08-25)
      Article
      Open Access
      Al-3Mg alloy reinforced with B4C particles in volume fractions of 5, 10 and 15% were subjected to hot deformation to investigate the impact of presence of ceramic particles and deformation condition on final texture. ...
    • Theoretical approach to Poisson ratio behavior during structural changes in metallic glasses 

      Pineda Soler, Eloi (Americal Physical Society, 2006-03)
      Article
      Open Access
      Recently, various studies dealing with the relationship between the elastic constants and various of the macroscopic properties of metallic glasses have been published. Particularly, the correlations between the Poisson’s ...
    • Thermal and oxidation stability of TixW1−x diffusion barriers investigated by soft and hard x-ray photoelectron spectroscopy 

      Kalha, Curran; Fernando, Nathalie Kanchena; Berens, Judith; Gutierrez Moreno, Jose Julio; Mohr, Stephan (American Institute of Physics, 2021)
      Article
      Open Access
      The binary alloy of titanium-tungsten (TiW) is an established diffusion barrier in high-power semiconductor devices, owing to its ability to suppress the diffusion of copper from the metallization scheme into the surrounding ...
