Surface Textures in Cold Rolled or Recrystallized Silicon Iron Single Crystals

Abstract

Cold rolled textures at the surfaces of (011) [100] - and (001) [110] -oriented 3%Si-Fe single crystals which were rolled with various lubricants, e. g. sheets of paper, plastic film, as well as conventional oil were tudied. In the (010) [100] crystals rolled by 60%, preferred surface texture was (011) [100] when no lubrication was used, whereas in the case of using adhesive paper labels pasted on the surface the texture was {111} <211> which coincided exactly with the midplane texture. A slip mechanism was proposed to explain the formation of surface textures at frictional surfaces.
Preferred recrystallization texture originating from the surface of large friction of the (011) [100] crystal was found to have the same orientation as the minor recrystallization texture at the midplane. Surface textures and their control were suggested to be important to control secondary recrystallization texture when cold rolled sheets were annealed.
