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).Artigo IPEN-doc 17321 Microstructural and mechanical evaluation of the surface hardening treatment using an Nd: YAG pulsed laser on aluminum-silicon used in the automobile industry2011 - MONTEIRO, W.A.; SILVA, L.V.; ROSSI, W. de; SILVA, E.M.R.; BUSO, S.J.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.Artigo IPEN-doc 15879 Estudos dos mecanismos envolvidos em processos de endurecimento superficial a laser de ligas a base de aluminio2010 - SILVA, L.V. da; BUSO, S.J.; SILVA, L.C.E. da; ROSSI, W. de; MONTEIRO, W.A.Artigo IPEN-doc 15559 Microstructural and mechanical characterization of gray cast iron and AlSi alloy after laser beam hardening2010 - MONTEIRO, W.A.; SILVA, E.M.R.; SILVA, L.V.; ROSSI, W. de; BUSO, S.J.
