Abstract Rolling textures and recrystallization textures have been studied in iron siliconalloys containing silicon 4.15%,2.9% and 3.35% respectively.X-ray pole figures haveshown that rolling textures can be described as(001)[110],(112)[110]and(111)[112]in all alloys after cold reductions greater than 60%.Upon annealing,recrystalli-zation textures are as follows:(001)[110]with a rotation of 0°-30° about[001]axis,(111)[112]and(110)[001].The mechanism of formation of recrystallization textures has been investigated bysuccessive stages of annealing.The following conclusions have been obtained:1)The(100)[110]texture having a rotation of 0°-30° about[001]axis wasdeveloped through the process of“recrystallization-in-situ”.2)Since the intensity of(110)[001]annealing texture seemed to vary in cor-respondence with the intensity of(111)[112]rolling texture,the mechanism of(110)[001]formation could be considered preferably from the point of view of“orientednucleation”hypothesis.3)There existed a definite sequence of disappearance of the various rolling texturecomponents,the(111)[112]texture disappeared first and the(001)[110]last.Thisobservation is in agreement with what has been found in single crystals of iron silicon.However,it is shown that this capability of recrystallization does not depend on therelative amount of the given rolling texture present,rather it depends on the type ofthe given texture itself.
