【摘要】 分析了退火对铁基非晶合金磁性的影响及其作用机制。退火使淬态Fe₇₉B₁₆Si₅非晶合金的饱和磁感应强度提高了72%,矫顽力降低86%,损耗和激磁功率分别下降83%和76%。退火后非晶态合金磁性的改善,主要归因于条带内应力的松弛。更多还原

【Abstract】 The effect an dmechanism of annealing on the magnetism of Fe-based amorphous alloys has been analyzed.After annealing,the saturation induction B₅ of as-quenched amorphous Fe₇₉B₁₆Si₅ alloy ia increased by 72%,concurrently with the reduction of coercive force H_c by 86%.The power loss P and excitine power P_e are also decreased by 83%and 76%,respectively.The improvement of magnetic properties is primarily bue to the effective removal of the internal stress during the annealing process.更多还原
