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.Resumo IPEN-doc 17701 Nanosystems developing of pharmaceutical in pseudoboehmites2011 - MUNHOZ JUNIOR, A.H.; MARTINS, M.V.S.; USSUI, V.; CARRIO, J.A.G.; MIRANDA, L.F.Resumo IPEN-doc 18433 Síntese e caracterização microestrutural de ligas a base de cobre, n´quel, prata e nanoparticulas de ítria - estudo das propriedade elétricas e mecânicas2012 - MONTEIRO, W.A.; OKAZAKI, A.K.; CARRIO, J.A.; BARROS, H.D.A.S.; PEREIRA, R.M.S.; MARTINS, M.V.S.Artigo IPEN-doc 15872 Refinamento pelo metodo de Rietveld de uma chapa laminada com orientacao preferencial da liga Al-Mg-Si 60632010 - CARRIO, J.A.G.; LIMA, N.B.; COUTO, A.A.; AGUIAR, A.A.; HATTORI, C.S.; MIRANDA, L.F.; DOMINGUES JUNIOR, N.I.Artigo IPEN-doc 15865 Structural and microstructural comparative analysis on metallic alloys of composition Cusub(y%)-Nisub(x%)-Me (Me=Sn,Cr,Al,Pt)2010 - MARQUES, I.M.; OKAZAKI, A.K.; SILVEIRA, C.R. da; CARVALHAL, M.A.; MONTEIRO, W.A.; CARRIO, J.A.G.Artigo IPEN-doc 15864 Comportamento eletrico e mecanico de ligas metalicas ternarias a base de cobre niquel obtidas por metalurgia do po2010 - MONTEIRO, W.A.; CARRIO, J.A.; CARVALHAL, M.A.; MARQUES, I.M.; SILVEIRA, C.R. da; SILVA, G.F.Artigo IPEN-doc 17927 Low temperature effect in electrical properties of sintered copper-nickel-aluminium alloys2011 - 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. da
