用磁滞回线和弯曲试验研究了Fe_（73.5）Cu_（11）Nb_（33）Si_（13.5）B_9合金在不同退火和中子辐照处理后的磁性能和力学性能的变化。结果表明，非晶合金的退火温度略高于其晶化温度，导致形成平均晶粒直径约为11 nm的超细晶粒结构的α-Fe（Si）嵌入非晶基体。所得纳米晶样品表现出非常好的软磁性能，但其机械性能恶化。为了评估和比较非晶和纳米晶样品对辐射损伤的耐受性以及相关的微观结构变化，在堆芯反应堆位置对所研究的合金样品进行了辐照。在纳米晶样品的情况下，中子辐照后的软磁性能的劣化被认为是不太显着。研究了试样的脆化状态。
The changes in the magnetic and mechanical properties of Fe73.5Cu1Nb3Si13.5B9 alloys after various annealing and neutron irradiation treatments were studied by hysteresis loop measurements and by bending tests. It was shown that annealing of the amorphous alloy slightly above its crystallization temperature leads to the formation of an ultrafine grain structure of α‐Fe(Si) with an average grain diameter of about 11 nm embedded in an amorphous matrix. The resulting nanocrystalline samples exhibit very good soft magnetic properties but their mechanical properties are deteriorated. In order to evaluate and compare the resistance of amorphous and nanocrystalline samples to radiation damage and the correlated microstructural changes, specimens of the alloys investigated were irradiated in the in‐core reactor position. Deterioration of the soft magnetic properties after neutron irradiation was found to be less significant in the case of nanocrystalline samples. The state of embrittlement of the samples investig...
