けい素鋼板における1次再結晶粒径，集合組織および析出分散相に及ぼすSi含有量の影響

Abstract

A study has been made on the effect of the increase of Si content on the primarily recrystallized structure, texture and the dispersion of precipitates in the grain-oriented electrical steel produced by the single-stage cold rolling process by use of MnS and AlN as inhibtors.(1) The size of primary grains increases. This is considered to be attributed to the larger size and coaser dispersion of precipitates in the specimen with higher Si content.(2) The amount of nuclei with Goss texture decreases. This is considered to be attributed to the less amount of free C during cold rolling, which is cosidered to decrease the amount of transition bands in the specimen with higher Si content.(3) The size of precipitates increases and their dispersion gets coaser. This is considered to be attributed to the less uniformity of structure and content of elements in the specimen with higher Si content.(4) From the three points mentioned above, it is considered that higher content of Si makes secondary recrystallization more difficult.
