摘要
利用OM、SEM、TEM等实验方法研究了卷取工艺对一种新型含铜无取向电工钢晶粒度和析出相的影响。结果表明,该电工钢热轧带卷取后的晶粒尺寸为18～24μm,在卷取过程中,热轧带中有一定数量的第二相析出,经EDS能谱及选区电子衍射分析,这些析出相主要为AlN。随着卷取工艺的变化,该电工钢的晶粒度大小变化不明显,析出相的类型、尺寸大小不发生改变,体积分数发生一定的改变。
The effects of coiling process on grain size and precipitates of a new copper-bearing non-oriented electrical steel were investigated by OM, TEM and other experimental method. The results show that the grain size of hot-rolled bands after coiling is 18 -24 μm. The second phases precipitate during coiling process. They are mainly AIN by EDS spectra and selected area electron diffraction. With the change of coiling process, the grain size of the electrical steel does not change significantly; the type and size of precipitates do not change, but certain changes occur in the volume fraction.
