Structural Evolution of IF Steel during Annealing after ECAP
IF steel processed by equal channel angular pressing to an equivalent strain of 9.2 via route BA was annealed for different times at 500°C and 600°C. At both temperatures the microstructural evolution shows continuous recrystallization followed by grain growth, in absence of primary recrystallization. At 600°C a slightly bimodal grain size distribution develops.
