Effect of Nb and C on the hot flow behavior of Nb microalloyed steels
Materials & Design (1980-2015)(2014)
摘要
•The effects of Nb and C on hot flow behavior of Nb microalloyed steels were investigated.•Nb addition increases the hot deformation flow stress while C addition generates a softening effect.•Nb addition increases the hot deformation activation energy while C addition reduces the hot deformation activation energy.•Nb addition increases the characteristic strains while C addition reduces the characteristic strains.
