Abstract
The rules of texture and grain boundary transformation in the nonoriented silicon steel under applied stress or without applied stress during grain growth were investigated by EBSD. The results show that the {111}<112> and {111} < 110> components in the nonoriented silicon steel without stress are strengthened during grain growth whereas {100} <001> component is weakened, but the growth rate of {111}(112> and {111} < 110> component decreases, while the area fraction of {100}<001> component doesn't change significantly in the sample under stress. For the {111) <112> , {111} <110> and {100} <001> components changing continuously during grain growth, the frequency of high angle mi-sorientation grain boundary of {111} <112> and {111} <110. components decreases, and that of {100} <001> component increases, and whereas the stress being applied in the sample, the frequency decreasing rate of {111} <112> and {111} <110> components rate becomes low and that increasing rate of {100} <001> component becomes a little lower. The segregation behavior of alloying agent in grain boundary was studied.关键词
