【摘要】 对定向凝固Fe-6.5%si合金进行热轧和退火处理。EBSD分析和磁性测定结果表明,热轧使定向凝固Fe-6.5%Si合金形成了Goss织构和大量小角晶界并产生了一定程度的加工硬化,从而使磁导率提高、剩磁和矫顽力增大。随后的退火处理使磁导率和剩磁进一步增大,但使矫顽力有所减小。更多还原

【Abstract】 Directionally solidified Fe-6.5%S alloy was hot-rolled and then annealed. The results of EBSD analyses and magnetic tests show that after hot rolling, large quantities of small angle grain boundaries, Goss texture, and some work hardening occur, which in turn increases the permeability, residual induction, and coercive force. The succedent annealing treatment increases the permeability and residual induction further, but reduces the coercive force to some extent.更多还原
