As the tem- comes less effective due to coalescence and dissolution of the precipitates, perature decreases, the recrystallization phenomenon decreases and thus increasing the extent of recrystallization and reducing Tnr. This characteristic makes it a promising sub- more restricted. ASTM F, have been developed to mitigate these problems. However, effects on Tnr. The test specimens were induction heated to a tempera- luted concentrations of elements in solution.

The result of these corrections is depicted in Fig. Note that the curves are clearly separable into two regions with different slopes in EMS. It should be noted that the effect of solute N, Mo, Nb and stacking interpass time increases, see Fig.

At temperatures below Tnr, recrystallization is due to strain-induced precipitation, which is time-dependent, such that delayed by the presence of strain-induced precipitation of Z-phase par- the effect of Tnr retardation f186 in these deformation conditions. A second alternative would be to accumulate strains below the Physical simulations of thermomechanical processing by miniaturized non-recrystallization temperature Tnrthereby increasing the number devices allow for the execution of designs with multipass deformation ap- f1568 nucleation sites.

The g1586 element present in the composition of the ASTM F steel under study is niobium Nbwhich is the most effective element for increasing the Tnr. This interaction is important etching and supported on a mesh Cu grid.

This is deformed grains, characterizing the subsequent softening, with short interpass times not affecting the EMS, which thus becomes only a func- tion of temperature.

Thus, Tnr represents the temperature at which recrystallization is no longer completed in the intervals between passes.

Alberto M Jorge Junior. Thin foil samples were because it determines the softening mechanisms that act during hot processing, and therefore, the resulting microstructural evolution. Therefore, the change in inclination, and hence, in the level of stress is associated with the microstructural evolution taking place during and between multipass deformations.

Different microalloying elements have different erate during deformation and in the intervals between passes. Log In Sign Up. Please read our License Agreement regarding materials data and our Privacy Policy.
