采用不同的旋轮转速，采用熔融旋压法成功地制备了Ni45Mn36.6In13.4Co5磁性形状记忆合金的择优织构薄带。利用X射线衍射（XRD）和电子背散射衍射（EBSD）研究了这些快淬薄带的结构和织构演变。根据10 m/s、15 m/s和20 m/s的轮速，熔纺带的厚度分别为42 μ m、65 μ m和30 μ m。纤维织构的密度（（100）//ND）随轮速的变化而变化，在轮速为15 m/s时，纤维织构的密度最大。在873 K、973 K、1073 K和1173 K退火后，薄带的晶粒长大，在873 K退火后，薄带没有再结晶现象，而在更高温度退火后，薄带发生了再结晶。不同温度退火后，由于退火过程中形成了新的再结晶织构，纤维织构有所减弱。(C)2016 Elsevier Inc.

Ni45Mn36.6In13.4Co5 magnetic shape memory alloy was successfully produced as preferentially textured ribbon by melting spinning with different wheel speed. X-ray diffraction (XRD) and electron back scatter diffraction (EBSD) were used to study structure and texture evolution of these melt-spun ribbons. The thickness of melt-spun ribbon is 42 pm, 65 pm and 30 pm depending on wheel speed of 10 m/s, 15 m/s and 20 m/s, respectively. Density of a fiber texture ((100)//ND) vary with wheel speed changes, and is most intensive in the ribbon with wheel speed of 15 m/s. Grains of the ribbons grow after being annealed at 873 K, 973 K, 1073 K and 1173 K, recrystallization was not observed in ribbons after being annealed at 873 K but occurred in ribbons after being annealed at higher temperatures. The et fiber texture becomes weaker to some extent after annealing at different temperatures, due to new recrystallization texture formed at the process of annealing. (C) 2016 Elsevier Inc.
