铁硅合金(110)[001]单晶体的形变和再结晶

本文研究了含硅3.25％铁硅合金(110)001]的单晶,在压下量为5—50％范围内的形变和再结晶。沿样品轴向冷轧2—16％后,测出的滑移面为(101),(101),(011)和(011),孿生面为(112)和(112),这很好地解释了本文所得冷轧机构的来源。样品经过35％和50％冷轧后,在退火时再结晶晶粒形成的部位和生长的情况有所不同:前者在孿晶界上领先形成,并沿孿晶界择尤生长;而后者除了观察到在孿晶界和形变带附近形成外,还观察到一种通过亚晶粒长大而成的晶粒,它们择尤生长的趋势也不如前者明显。

DEFORMATION AND RECRYSTALLIZATION IN (110) [001] SINGLE CRYSTALS OF IRON-SILICON ALLOY

This paper described deformation and recrystallization in (110)00l] single crystals of iron-silicon (3.25%) which reduction of thickness 5-50%. In the range of a reduction 2-16%, the slip planes ate (101), (101), (110) and (Tl0); and the twinning planes are (112) and (112). Which coincided satisfactorily with our explanation on the formation of cold-rolling textures in (110) 001] singe erystals of iron-silicon alloy.We observed that the position and growing process of recrystallized grains are difference between cold-rolling 35 % and 50 % with annealing treatment. The recrystalized grains of the former formed first at twinning boundary and preferred growth along the twinning boundary. But the latter may be formed by subgrain except forming at twinning boundary and near the deformation bands, and the preferred growth is not as apparent as former.
