Resumo
High 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).
