Friction stir welds are considered reliable joints for their lack of voids, cracks and distortions. When compared to the base material, friction welding (FSW) typically exhibit finer grain structured (especially at nugget zone, NZ). Similarly, refined structure can also be obtained by severe plastic deformation (SPD) techniques, such as equal channel angular pressing (ECAP). In fact, fine structures produced within NZ FSW or processed (FSP) materials usually coarser than ones achieved ECAP....
A basic model was applied to pure Ni and then a single-phase superalloy. The high temperature deformation of the superalloy, solution treated IN718, investigated by torsion testing in high-temperature regime (1000–1100 °C) where no precipitation secondary phases expected. material exhibited classical behaviour alloys which undergo dynamic recrystallization. peak-flow stress dependence on strain-rate described physically-based set constitutive equations, took into account both dislocation...
