摘要
通过真空感应熔炼出Ni4WxV(x=2,4,6)合金,采用轧制辅助双轴织构基带技术制备出厚度200μm的合金基带。测量合金基带的磁性能和屈服强度;采用X射线衍射技术(XRD)及电子背散射衍射技术(EBSD)分析比较不同成分合金基带的冷轧织构和再结晶织构,并与Ni5W合金基带进行比较,得出综合性能更优的成分。结果表明,Ni4W2V合金基带综合性能最佳,其屈服强度为150.7 MPa,与Ni5W合金基带相当;常温下饱和磁化强度为Ni5W合金基带的55%,立方织构含量为56%(<30°),极具研究前景。
Ni4WxV（x=2,4,6）alloys were produced by vacuum induction melting,and 200μm thick alloy substrate tapes were fabricated by rolling assisted biaxial texture substrate tape technology.The magnetic properties and yield strength of the alloy substrate tapes were measured.By using X-ray diffraction（XRD）and electron backscattering diffraction（EBSD）,the cold rolling texture and recrystallization texture of the alloy substrate tapes with different composition were analyzed and compared with those of Ni5 Wsubstrate tape,to select the composition with better comprehensive performance.The results show that Ni4W2V alloy substrate tape has the best comprehensive performance with yield strength of 150.7 MPa,which is equivalent to Ni5 Walloy substrate tape.Ni4W2V alloy substrate tape has 55%saturation magnetization of Ni5 Wat room temperature,and its cube texture content is 56%（〈30°）.Therefore,Ni4W2V is a promising alloy composition.
