Hot deformation behaviour of Fe-21Cr-15Ni-Nb-V stainless steel was investigated by isothermal compression in the temperature range of 950-1150°C with a strain rate of 0.01-10 s −1 . The results showed that complete recrystallisation occurred beyond 1050°C, resulting from the pinning effect of (Nb, V...
