| Popis: | Due to the rapid growth of precipitated nanoparticles in ultrahigh Fe content nanocrystalline alloys, we propose a new method of low-pressure stress annealing (LPSa) to control crystallization behavior to achieve excellent magnetic properties and mechanical properties of Fe85.7Si0.5B9.3Cu0.7P3.5C0.3 nanocrystalline alloy. It demonstrates that LPSa promotes the precipitation of α-Fe phase and suppresses the growth of nanoparticles, which obtains a higher saturation magnetization of 202.1–206.6 emu/g and a lower coercivity of 6.7–8.2 A/m. Besides, the formation of fine and uniform nanocrystalline structure induced by LPSa achieves the lower value and uniform distribution of hardness and Young's modulus, resulting in softening. |
