1935年Goss首先制成具有(110)[001]织构(也称为戈斯织构)的晶粒取向硅钢片,由于[001]方向是易磁化方向,因此沿轧向使用这种钢片时能获得高的磁性,但横向磁性很差。现在已经发展到晶粒平均取向([001]方向与轧向之间的平均角度)大约只偏离8°。表1是这种高级取向硅钢片与高级无取向热轧硅钢片的磁性比较。如果能发展(100)[00l]立方织构,它将比戈斯织构具有更大的用途。这种织构在面心立方体金属中是常见的,并已应用在铁镍磁性合金;但长期以来人们都认为在体心立方体金属中不可能产生立方织构。
Goss first made in 1935 with (110) [001] texture (also known as Goss texture) grain oriented silicon steel sheet, since the [001] direction is the direction of easy magnetization, so the rolling direction of the use of such steel When to obtain high magnetic, but transverse magnetic poor. It has now been developed that the average orientation of the grains (the average angle between the [001] direction and the rolling direction) deviates by only about 8 °. Table 1 shows the magnetic comparisons between this high-grade oriented silicon steel sheet and the high-grade non-oriented hot-rolled silicon steel sheet. If we can develop (100) [00l] cubic texture, it will have a greater use than the Goss texture. This texture is common in face-centered cubic metals and has been used in ferromagnetic iron alloys; however, it has long been believed that cubic texture can not be created in body-centered cubic metals.
