| Abstract: | With a Gleeble 1500 thermal simulator,research was made on the recrystallization behavior of the 9Cr 1Mo V Nb N ferrite heat resistant steel under the deformation conditions,i.e.temperature range of 850～1 250℃ and deformation rate of 0.01～10s -1 .As a result,the boun dary conditions under which recrystallization of the said steel occurs during thermal deformation thereof was obtained and the plasticity chart and the recrystallization chart produced. |
