研究硅含量为 6 .5 %的高硅钢有序相消失是为了降低能耗、提高经济效益。试验采用传统的铸造或成形方法进行 ,然后利用透射电子显微镜进行研究。试验过程中发现 ,改变试样的制造方法对抑制 Fe- Si二元系合金中的有序相 B2 没有影响。研究结果表明 ,硅含量为 6 .5 %的高硅钢中的 Studying the order phase loss of high silicon steel with 6.5% silicon content is to reduce energy consumption and improve economic efficiency. The tests were performed using conventional casting or forming methods and then studied using transmission electron microscopy. During the test, it was found that changing the method of manufacturing the sample did not affect the suppression of the ordered phase B2 in the Fe-Si binary system alloy. The results show that the silicon content of 6.5% of the high-silicon steel
