对0.20 mm厚新能源汽车用无取向硅钢在不同退火温度下的组织、织构、力学性能及磁性能进行了系统研究。结果表明,780 ℃/3 min时已经完成了再结晶,在再结晶初始阶段,λ织构主要在冷轧后的晶内剪切带形成,同时,也会形成部分{114}<841>和{112}<110>,以及{111}<112>取向晶粒。而冷轧非剪切带区域主要生成{114}<841>、{112}<241>取向的α*织构和{100}<120>织构。退火温度≥900 ℃时,随温度升高,{111}<112>织构占比逐渐减小,{100}<001>织构占比逐渐增多,退火温度升高会促进λ织构的生成,且抑制γ织构的生长。晶粒尺寸随着退火温度的升高而增大,高频铁损P1.0/400先降低再升高,在920~960 ℃达到最小值,此时,晶粒尺寸在108~138 μm,也是最佳晶粒尺寸范围。强度随着退火温度升高逐渐降低,在920~960 ℃基本保持恒定。
This study systematically investigates the microstructure, texture, mechanical properties, and magnetic properties of 0.20 mm thick non-oriented silicon steel for new energy vehicles under different annealing temperatures. It is observed that recrystallization had finished at 780 ℃. In the initial stage of recrystallization,λ fiber texture mainly formed in the cold-rolled shear bands, and some {114}<841> and {112}<110>, and {111}<112> oriented grains are also formed there.The α* fiber texture of grains with orientation of {114}<841>,{112}<241> and {100}<120> is mainly formed in the other zones.When annealing at 900 ℃ and above,As the annealing temperature rises, the proportion of {111}<112> components diminishes gradually, while the proportion of {100}<001> components grows slowly. This augmentation in annealing temperature will foster the formation of λ fiber texture and impede the growth of γ fiber texture. Grain size increases with the rise in annealing temperature, yet the high frequency iron loss P1.0/400 initially declines before eventually rising to its lowest value.in the range of 920 ℃-960 ℃, and the grain size range is 108 μm-138 μm, which is also the best grain size range.As the annealing temperature rises, the strength diminishes gradually and remains nearly invariable in the 920 ℃-960 ℃ range.
