Artigo IPEN-doc 22584 Structural analysis by the Rietveld method and SEM of irradiated pseudoboehmite and Al2O32007 - CARRIO, J.A.G.; FALDINI, S.B.; MIRANDA, L.F. de; KIYOHARA, P.K.; SILVA, L.G.A.; MUNHOZ JUNIOR, A.H.Artigo IPEN-doc 20788 Study of electrical, mechanical and microstructural properties of composites based on Cu-Ni-Ag-Alsub(2)Osub(3) obtained by powder metallurgy2014 - MONTEIRO, WALDEMAR A.; CARRIO, JUAN A.G.; OLIVEIRA, E.C.; PREVIATTI, G.G.; SILVA, L.C.E.The synthesis, microstructural, electrical and mechanical properties characterization of composites based on Cu-Ni–Ag-Al2O3 is a work that exposes the investigation of the correlation of the microstructures formed in the material with its physical properties and its manufacturing method. Cermets based on copper, nickel and silver have been doped with alumina varying the proportions of these components to create, by powder metallurgy, a material that has good electrical conductivity and good mechanical strength compared with that of pure copper, together with a manufacturing process which is both cost and energy efficient. The conductivity values vary between 30 to 55% IACS showing that the thermal treatments were effective for electrical connector uses.Artigo IPEN-doc 20789 Electrical, mechanical and microstructural properties of copper-chromium-silver-alumina composites obtained by powder metallurgy2014 - MONTEIRO, WALDEMAR A.; CARRIO, JUAN A.G.; SANTOS, M.A.R.; MOTTA, D.S.; SILVA, L.C.E.Artigo IPEN-doc 20792 Low temperature effect in electrical properties of sintered copper-nickel-aluminium alloys2015 - MONTEIRO, WALDEMAR A.; CARRIO, JUAN A.G.; SILVEIRA, CLAUDIA R. da; CARVALHAL, MARCELO; MASSON, TEREZINHA J.Artigo IPEN-doc 16562 Microstructure and microanalysis studies of copper-nickel-tin alloys obtained by conventional powder metallurgy processing2010 - MONTEIRO, W.A.; CARRIO, J.A.G.; MASSON, T.J.; ABREU, C.D.; MARQUES, I.M.; SILVA, L.C.E. daArtigo IPEN-doc 16561 Structural and electrical properties of copper-nickel-aluminium alloys obtained by conventional powder metallurgy method2010 - MONTEIRO, W.A.; CARRIO, J.A.G.; SILVEIRA, C.R. da; VITOR, E.; BUSO, S.J.Artigo IPEN-doc 16540 Microstructural and electrical investigation of Cu-Ni-Cr alloys obtained by powder metallurgy method2010 - CARRIO, JUAN A.G.; CARVALHAL, M.A.; AYABE, L.M.; SILVA, L.C.E. da; SILVA JUNIOR, R.V.; MONTEIRO, W.A.
