Recovery and Recrystallization Behaviors of Ni–30 Mass Pct Fe Alloy During Uniaxial Cold and Hot Compression

Abstract The recovery and recrystallization behaviors of the high-temperature ? -phase carbon steel during deformation strongly affect mechanical properties steel. However, it is difficult to evaluate such at a high temperature. This study proposes behavior low-carbon based on quantitative observation dislocation density vacancies in Ni–30 mass pct Fe alloy. alloy was used because its stacking fault energy (60 70 mJ m -2 ) similar that Uniaxial compression tests were conducted strain rate 10 ?3 s ?1 1473 K (1200 °C) for dynamic 293 (20 work hardening. process interrupted different values systematically investigate microstructural changes. changes hardening, recovery, obtained from true stress–true curves uniaxial tests. Further, microstructure cold hot investigated viewpoint lattice defects by X-ray diffraction, positron annihilation analysis, transmission electron microscopy, backscatter diffraction comprehend (DRV), (DRX). helps understand DRV, DRX, hardening compression.
