| 摘 要： | 采用质子加速器对Fe-Ni软磁合金进行8MeV质子辐照,研究其磁性能及组织结构与缺陷变化情况。研究结果表明,随质子辐照吸收剂量的增加,Fe-Ni合金的矫顽力增大,磁导率下降,饱和磁感应强度未受影响。X射线衍射(XRD)结果表明辐照未引起相结构的变化,但使晶格发生了畸变。正电子湮没分析表明,辐照导致了空位等材料缺陷。 |
| 关 键 词： | Fe-Ni软磁合金 质子辐照 材料缺陷 试验研究 |

| Abstract: | A radiation experiment with 8 MeV proton was carried out with an accelerator to study the magnetic property and the microstructure as well as the flaw distribution of the Fe-Ni soft magnetic alloy.It is shown that after the proton radiation,the coercivity of the Fe-Ni soft magnetic alloy goes up with the increase of the absorbed dose and the decrease of the magnetic permeability.The saturation magnetic induction remains stable.The XRD results show that irradiation does not cause phase changes in the structure,but causes lattice distortions.The positron annihilation analysis shows that the irradiation leads to vacancies and other flaws. |
| Keywords: | Fe-Ni soft magnetic alloy proton irradiation material flaw experimental study |
