It is observed that in the early stage, theminor fine grains were found along the original grain boundaries, and under thefurther increasing strain, the intragranular nucleation became more predominate.The stronger dynamic recovery results in a lot of well-defined subgrains. The strainwill induce the subgrain rotation together with the subboundary coalescence andform new grains. An observation also revealed that lattice orientation betweendynamic recrystallization grains is formed from the progressing rotation in "tilt"or "torsion" of subgrain in the original grains. It seems that the dynamic recrys-tallization nucleation of Cr25Ti steel is similar to several minerals in that bothare nucleated homogeneously by the strain inducing progressing rotation of sub-grains. However, a high degree of "asynchronism" during dynamic recrystallizationcauses no obvious peak on the stress-strain plot.
