摘要:
This study is to fabricate a composite substrate (Ni7W/Ni12W/Ni7W) with weak magnetization, strong reinforcement, and improved cube texture via Rolling Assisted Biaxially Textured Substrates (RABiTS) route. The formation of cube texture with reduction in twin boundaries due to recrystallization annealing was investigated thoroughly. The optimized recrystallization annealing process revealed 97.4% of cube texture and 83.9% of small angle grain boundaries at an angle of (<10 degrees). Higher W content and presence of defects (holes, dislocations, and grain boundaries) within inner layer of the substrate restricted the formation of cube texture along the normal direction (ND), as compared to rolling direction (RD). Furthermore, significant improvement in mechanical strength (sigma(0.2) = 205 +/- 2 MPa) and saturation magnetization (2.6 emu/g) was found for Ni7W/Ni12W/Ni7W as compared to Ni7.5W substrates.
