Artigo IPEN-doc 23181 Characterization of nickel alloy 600 with ultra-fine structure processed by Severe Plastic Deformation technique (SPD)2017 - MONTEIRO, WALDEMAR A.; SILVA, SILVIO L.V. da; SILVA, LUCIANA V. da; ANDRADE, ARNALDO H.P. de; SILVA, LUIS C.E. daHigh strength nickel based alloys are used in a multitude of advanced systems where lightweight, high power density mechanical power transmission systems are required. Components such as gears, bearings and shafts could be made significantly smaller and more durable if a major improvement in nickel based alloy mechanical properties could be achieved. An important refinement in grain size (includes nanometric level) is thought to be a promising method for achieving fundamental improvements in mechanical properties. Grain size is known to have a significant effect on the mechanical behavior of materials. One of the most favorable methods of achieving extreme grain refinement is by subjecting the materials to severe plastic deformation (SPD). The principal microstructural variations in superalloys are the precipitation amount and morphology, grain size and the distribution of carbide precipitation that could reduce the mechanical properties of the alloys. This work shows optical and transmission electron microscopy analysis and also hardness data after severe plastic deformation (pure shear stress).Resumo IPEN-doc 22202 Microstructural characterization of aluminium alloy AA1050 with ultrafine structure obtained by intense plastic deformation (ECAP)2015 - GUERRA, M.C.L.; MONTEIRO, W.A.; FERREIRA, N.A.M.; SILVA, L.C.E.Artigo IPEN-doc 20801 Characterization of nickel alloy 600 with ultra-fine structure processed by severe plastic deformation technique (SPD)2014 - MONTEIRO, W.A.; SILVA, S.L.V.; SILVA, L.V.; ANDRADE, A.H.P. de; SILVA, L.C.E.Resumo IPEN-doc 06150 The relationship between the manganese sulfide precipitation during hot compression process with one and two holding time in grain oriented electrical steel1997 - RODRIGUES, V.A.; MONTEIRO, W.A.; SALIBA SILVA, A.M.; FERREIRA, N.A.M.; SILVA, L.C.E.Resumo IPEN-doc 05963 Estudo da precipitacao de particulas de MnS na liga de Fe-3 porcento Si apos ensaio de compressao a quente1995 - RODRIGUES, V.A.; MONTEIRO, W.A.; FERREIRA, N.A.M.; SILVA, L.C.E.; CUNHA, M.A.; SALIBA SILVA, A.M.Resumo IPEN-doc 09027 Transmission electron microscopy in the microstructure study of electrical steel Fe-3 percent Si1998 - RODRIGUES, V.A.; MONTEIRO, W.A.; SALIBA SILVA, A.M.; FERREIRA, N.A.M.; SILVA, L.C.E.Resumo IPEN-doc 02181 Avaliacao do efeito do tempo de solubilizacao de particulas de MnS no aco Fe-3 porcento Si por microscopia eletronica de transmissao1993 - RODRIGUES, V.A.; MONTEIRO, W.A.; FERREIRA, N.A.M.; SILVA, L.C.E.; SILVA, A.M.S.; CUNHA, M.A.Artigo IPEN-doc 05395 Influencia da precipitacao do MnS na liga Fe-3 porcento Si apos ensaios de compressao a quente1994 - RODRIGUES, V.A.; MONTEIRO, W.A.; FERREIRA, N.M.A.; SILVA, L.C.E.; CUNHA, M.A.; SALIBA SILVA, A.M.Artigo IPEN-doc 05634 Efeito do tempo de precipitacao da particula de MnS durante deformacao a quente por MET1994 - RODRIGUES, V.A.; MONTEIRO, W.A.; FERREIRA, N.M.A.; SILVA, L.C.E.; CUNHA, M.A.; SALIBA SILVA, A.M.Artigo IPEN-doc 05032 Estudo da precipitacao da particula de MnS apos ensaio de compressao a quente com dois passes de deformacao1996 - RODRIGUES, V.A.; MONTEIRO, W.A.; SALIBA SILVA, A.M.; FERREIRA, N.A.M.; SILVA, L.C.E.; CUNHA, M.A.
