<正> 一、引言具有体心立方品格的α-Fe的织构早为许多研究者所注意,可是所用材料大多为低碳钢或Fe-Si合金。对于纯铁的数据比较少见.G.Kurdjumov和G.Sachs曾进行电解铁的轧制和再结晶织构的研究,压延率为98.5%,而没有叙及易磁向的再结晶织构.最近Haeβner和Weik用交叉轧制法研究化学方法制备的纯铁,经80%压延率在580℃熟炼150分后,得到易磁化取向.可是用普通方法轧制获得易磁向强构的资料就少见到.

The rolling and recrystallization textures of armco iron are measured by magnetictorque method.Samples after hot-rolling are then cold rolled in three different ways;i.e.,thepercentages of the cold reduction are(i)73,(ii)65 and(iii)22.The class Ⅰ andclass Ⅲ material are annealed for one hour either at 700° or 850℃,and then givena second cold roll,the reduction of class Ⅰ material being this time 65 per cent andclass Ⅲ material being 55 per cent.All these samples in these three categories aregiven a final anneal at 870℃ in hydrogen for ten hours.The textures of the samples through one cycle of cold rolling are determined as(100)[011]and(112)[110].The textures of the material through two cycles ofcold rolling,with an intermediate anneal,are mainly(112)[110].The final annealedsamples with the possible exception of the class Ⅲ are estimated as having textures(110)[001]and(110)[001]+(100)[001].
