It was found that within the range of 0.007 to 0.040% aluminiumcontent (acid soluble) in silicon iron, the magnetic induction of the product,B_(10), could reach 18000 G until the temperature of the slab reheating prior tohot rolling was about 1250℃. With soluble aluminium contents outside thisrange, the value of B(10) was sharply decreased as the slab reheating temperaturewas lowered. The deformation structures and textures of the hot rolled sheetsin mid-thickness layer varied with the variations of the soluble aluminium con-tents in silicon iron as shown by the corresponding changes of structures afterprimary and secondary recrystallization. Although the role of aluminium playedin the silicon iron may be traced back prior to the hot rolling, it appears thataluminium mainly influences the deformation, dynamic precipitation of the secondphase and dynamic recrystallization processes of the material during hot rolling.Further studies are necessary to clarify the exact mechanism involved in theeffect of aluminium in grain-oriented 3% Si-iron.      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1977/V13/Iz1/80 [1] Littmann, F., Met.
