Cutting Texture of Fe-Si Alloy

The textures resulting from low speed cutting of Fe-3.14%Si alloy single crystals and polycrystalline specimens are examined by X-ray diffractometer. Some of results obtained are as follows. (1) Cutting the single crystals with various orientations, some preferred orientations were recognized in the deformed regions. (2) Cutting textures of polycrystalline specimens could be described as having {011} paral-lel to the cutting plane and parallel to the cutting direction. The dispersion of crystal orientation decreased with increasing grain size of those specimens. This {011} was characteristic component of textures in cutting surfaces, while it did not exsist in cold rolling textures of b. c. c. metals. (3) The main component {011} of the cutting textures of Fe-Si alloy was stronger in two pass cutting surface than one pass cutting surface.
