摘要

In 0.1 % Mn-added 3% Si-Fe alloys, the total number of {110} grains increased with increasing bulk sulfur content and with decreasing heating rate.This is contrary to that in Mn-free alloys.During isothermal annealing, the segregation concentration of sulfur for the initial time range was lower in the alloy containing 95ppm sulfur than that in the other alloy containing 25ppm sulfur.Also the maximum segregation concentration of sulfur appeared at a later time in the former.Such an annealing texture development and a segregation behavior can be attributed to the MnS precipitation and the subsequent dissolution into the matrix.
