生产由软磁合金制成的薄带材的方法以及所得到的带材
摘要：
用于生产能够被机械切割的由软磁合金制成的带材的方法，该软磁合金的化学组成以重量计包括：18％≤Co≤55％、0％≤V+W≤3％、0％≤Cr≤3％、0％≤Si≤3％、0％≤Nb≤0.5％、0％≤B≤0.05％、0％≤C≤0.1％、0％≤Zr+Ta≤0.5％、0％≤Ni≤5％、0％≤Mn≤2％，其余是铁和炼制中不可避免的杂质，根据所述方法，对通过热轧而得到的带材进行冷轧以得到厚度小于0.6mm的冷轧带材。在冷轧后，在介于该合金的有序/无序转变温度和该合金的铁素体/奥氏体转变开始温度之间的温度下，使通过连续炉，随后快速冷却至低于200℃的温度来进行连续退火处理。所得到的带材。
摘要（英）：

A method for manufacturing a strip in a soft magnetic alloy capable of being cut out mechanically, the chemical composition of which comprises by weight: 18%<=Co<=55%, 0%<=V+W<=3%, 0%<=Cr<=3%, 0%<=Si<=3%, 0%<=Nb<=0.5%, 0%<=B<=0.05%, 0%<=C<=0.1%, 0%<=Zr+Ta<=0.5%, 0%<=Ni<=5%, 0%<=Mn<=2%. The remainder being iron and impurities resulting from the elaboration, according to which a strip obtained by hot rolling is cold-rolled in order to obtain a cold-rolled strip with a thickness of less than 0.6 mm. After cold rolling, a continuous annealing treatment is carried out by passing into a continuous oven, at a temperature comprised between the order/disorder transition temperature of the alloy and the onset temperature of ferritic/austenitic transformation of the alloy, followed by rapid cooling down to a temperature below 200 DEG C. Strip obtained.
