研究证实了在纯氢气氛中，各向异性应变能对γ-α相变过程中温度梯度诱导形成{1 0 0}织构柱状晶组织的影响。结果表明，在纯氢气氛中，高温度梯度在γ-α相变过程中引起晶界应变能的显著差异，导致{1 0 0}织构的形成。由于其工艺简单，并能够获得良好的织构相关的磁性能，所提出的方法是有助于开发新型的无取向电工钢。
This study confirms the effect of anisotropic strain energy on the formation of {1 0 0} textured columnar grain structure induced by temperature gradient during γ to α phase transformation in pure hydrogen atmosphere. Results indicate that high temperature gradient in pure hydrogen atmosphere induces a significant strain energy difference across grain boundaries during γ to α phase transformation, leading to the formation of {1 0 0} texture with columnar grains. Given its simplicity in processing and its ability to obtain good texture-related magnetic properties, the proposed approach is helpful to the development of new types of non-oriented electrical steel.
