  • Alumina-Based Composites Reinforced with Ductile Particles 
    Osorio Ramos, Jessica J.; Refugio García, María Elizabeth; Terrés Rojas, Eduardo; MIRANDA HERNANDEZ, JOSE GUADALUPE; ROCHA RANGEL, ENRIQUE (International Journal of Research in Engineering and Science (IJRES), 2014-06-01)
    Al2O3/Metal composite ceramics were fabricated by the use of mechanical milling and pressureless sintering. Al2O3 + 10 vol.% of La, Mn, Si or Y were mixed and milled during 12 h at 300 rpm in a horizontal mill, then with ...
  • Alumina-Based Composites Reinforced With Silver Particles 
    ROCHA RANGEL, ENRIQUE; Refugio García, María Elizabeth; MIRANDA HERNANDEZ, JOSE GUADALUPE; Terrés Rojas, Eduardo (2014-01-01)
    Al2O3/Ag composite ceramics were fabricated by the use of mechanical milling and pressureless sintering. Al2O3 + 10 wt.% Ag were mixed and milled during 12 h at 300 rpm in a horizontal mill, then with the powder mixture ...
  • Ceramic Matrix Composites Reinforced with Metal Nanoparticles 
    Refugio García, María Elizabeth; Osorio Ramos, Jessica J.; ROCHA RANGEL, ENRIQUE; PEREZ DE LA FUENTE, AZUCENA; MIRANDA HERNANDEZ, JOSE GUADALUPE (WULFENIA JOURNAL, 2015-06-01)
    This project describes the formation of Al2O3-Ag or Al2O3-Ti nanocomposites via high-energy planetary milling combined with pressureless sintering. From the main results, it was found that after milling, the powder was ...
  • Forming Mullite-Ceramics Reinforced With ZrO2-t Starting From Mullite-ZrO2-t and Kyanite-Al2O3-ZrO2-t Mixtures 
    Refugio García, María Elizabeth; Osorio Ramos, Jessica J.; MIRANDA HERNANDEZ, JOSE GUADALUPE; RODRIGUEZ GARCIA, JOSE AMPARO; ROCHA RANGEL, ENRIQUE (2013-07-01)
    Mullite-ceramics reinforced with 8 and 10 vol. % YZT were prepared starting from two different powder mixtures. The first one was a mixture of pure mullite and YZT, and the other was a mixture of kyanite, alumina and YZT. ...
  • Fracture Toughness Enhancement of Mullite-Ceramics Reinforced with Metals 
    Refugio García, María Elizabeth; MIRANDA HERNANDEZ, JOSE GUADALUPE; RODRIGUEZ GARCIA, JOSE AMPARO; ROCHA RANGEL, ENRIQUE (WILEY, 2014-10-01)
    With the idea to determine ways of tailoring mullite-ceramics (3Al2O3∙2SiO2) in order that one or more toughening mechanisms are activated in service, investigations about the production of mullite-based composites with ...
  • Improving Fracture Toughness of Mullite Ceramics Metal Reinforcements 
    Refugio García, María Elizabeth; Osorio Ramos, Jessica J.; MIRANDA HERNANDEZ, JOSE GUADALUPE; RODRIGUEZ GARCIA, JOSE AMPARO; ROCHA RANGEL, ENRIQUE (International Journal of Research in Engineering and Science (IJRES), 2014-11-01)
    Mullite/Metal composite ceramics were fabricated by the use of mechanical milling and pressureless sintering. Al2O3 + 10 vol.% of Co, Ni, or Ti were mixed and milled during 12 h at 300 rpm in a horizontal mill, then with ...
  • Improving Toughness of Alumina-Based Composites to Be Used As Bone Substitute 
    Refugio García, María Elizabeth; MIRANDA HERNANDEZ, JOSE GUADALUPE; ROCHA RANGEL, ENRIQUE; OLEA MEJIA, OSCAR FERNANDO (International Journal of Engineering Research and Development, 2016-10-01)
    In this study it is show the experimental results of alumina reinforced with titanium additions, forming a composite which by its components could be classified as a biomaterial. The experimental results indicate that ...
