Abstract The effects of Nb addition on the recrystallization kinetics and recrystallized grain size distribution after cold deformation were investigated by using Fe-30Ni Fe-30Ni-0.044 wt pct steel with comparable starting distributions. samples deformed to 0.3 strain at room temperature followed annealing 950 °C 850 for various times; microstructural evolution non- fully characterized, along s...
