Fabrication of full density near-nanostructured cemented carbides by combination of VC/Cr3C2 addition and consolidation by SPS and HIP technologies

Bonache Bezares, Victoria; Salvador Moya, Mª Dolores; Fernández Valdés, Adolfo; Borrell Tomás, María Amparo (Elsevier, 2011-03)

The aim of present work is to study the effect of VC and/or Cr3C2 in densification, microstructural development and mechanical behavior of nanocrystalline WC-12wt.%Co powders when they are sintered by spark plasma sintering ...
Fabrication of ultrafine and nanocrystalline WC-Co mixtures by high energy milling

Bonache Bezares, Victoria; Salvador Moya, Mª Dolores; Busquets Mataix, David Jerónimo; Segovia-López, Francisco (MANEY PUBLISHING, 2009)

[EN] In this work ultrafine and nanocrystalline WC-Co mixtures were obtained by low energy milling in planetary ball mill. The effect of the processing conditions on the reduction and distribution of the grain sizes and ...
Raman scattering study of bulk and nanocrystalline PbMoO4 at high pressures

Vilaplana Cerda, Rosario Isabel; Gomis Hilario, Oscar; Manjón Herrera, Francisco Javier; Rodríguez-Hernández, P.; Muñoz, Alfonso; Errandonea, Daniel; Achary, S.N.; Tyagi, A.K. (American Institute of Physics (AIP), 2012-11-21)

High-pressure Raman scattering measurements have been performed in wulfenite (PbMoO4) for both bulk and nanocrystalline powders up to 22 GPa. Our Raman scattering measurements evidence the phase transition from the tetragonal ...
