  The sheet manufacturing process,which involves various solid-state transformations such as phase transformations,plastic deformation and thermally activated recovery processes,determines the texture of the finished product.The conventional process of flat rolling and annealing only offers limited degrees of freedom to modify the texture.After annealing a {111} recrystallization fibre in BCC alloys is commonly obtained.For flux carrying purposes,however,other texture components are required than the ones achievable by conventional processing.In the present paper it is shown that by severe plastic deformation of ultra-low carbon steel a texture can be obtained with increased intensity on the {001} fibre,which is of interest for magnetic applications.A similar texture is observed at the surface of Mn added low carbon steels by a mechanism of orientation selection,which involves the crystal anisotropy of the metal/vapour surface energy.It is also demonstrated that the conventional {111} deep drawing texture of IF steel can be obtained by a process of ultra-fast annealing(with a heating rate of more than 1000°C/s).Ultra-fast annealing also allows to significantly reduce the grain size of the finished product as compared to the conventionally processed IF steel.

小分子光伏材料具有化学结构确切、易于纯化以及合成可重复性好的特点。一方面相对于聚合物,小分子材料具有相对明确的结构-性质关系,因而其理化性质的可调节性更强;另一方面,小分子材料可适用于不同的器件制备工艺,例如真空蒸镀或湿法工艺。硼氟二吡咯(BDOIPY)功能染料是近二十年发展起来的一类新兴功能染料,因其具有良好的稳定性与光伏特性而被广泛的应用于各个领域。尤其是长吸收波长的BODIPY作为电子供体在
