Texture evolution by grain growth in cold-rolled and annealed {110}<001> Fe-3% Si single crystal containing no precipitates was investigated by SEM-ECP. Main findings were as follows. (1) Primary recrystallization texture after 60% cold reduction (108-mu-m) was {110}<001> and the texture evolved by grain growth was {120}<001>. (2) Primary recrystallization texture after 82.6% cold reduction (47-mu-m) consists of {441}<6 7 52> and {661}<2 5 42> and no substantial texture change occurred by grain growth. (3) The mechanism of the {120}<001> orientation evolution by grain growth is considered to be due to the inhibition effect of higher frequency of SIGMA-1 boundaries present in the primary matrix and the higher frequency of SIGMA-19a coincidence orientation relationship between the grains evolved by grain growth and the primary matrix grains. This mechanism can be considered to be the same as that of the secondary recrystallization in FCC alloys containing no precipitates.
