| 1 | Microstructure and Magnetic Properties of Fe-Ni Alloy Fabricated by Selective Laser Melting Fe/Ni Mixed Powders显示文摘Fe—Ni alloy,as a widely applied ferromagnetic material,is synthesized using selective laser melting(SLM).The chemical compositions and microstructure of the SLM Fe—Ni alloy are characterized by X-ray diffraction(XRD), energy dispersive X-ray spectroscopy and scanning electron microscopy.It was found that the samples exhibited fine grains with homogenous distribution when a low laser scanning velocity was used.Moreover,the magnetic properties of the samples with different laser parameters are also measured.It shows that the SLM Fe—30%Ni alloy possesses a low coercivity and high saturation magnetization.It also can be obtained that SLM is an alternative faster method to prepare soft magnetic material with complex shapes.Moreover,the magnetic properties can be influenced by the laser parameters. | Baicheng Zhang Nour-Eddine Fenineche Hanlin Liao Christian Coddet | 2013 | Journal of Materials Science & Technology2013，29，8： | 12 |
| 2 | 激光增材制造FeNi坡莫合金及其磁性能研究显示文摘以Fe-50%Ni预合金粉末为原材料,并采用激光选区熔化(Selective laser melting,SLM)技术制备坡莫合金,通过光学显微镜、X射线衍射、扫描电子显微镜等对采用不同工艺参数制备的SLM Fe-50%Ni合金的微观组织进行观察表征,分别在直流及交流条件下采用磁性能测试仪对其稳态磁性能及动态磁性能进行测试分析,其中直流测试中最大外磁场强度为5000 A/m.同时,研究了在交流条件下外磁场强为10 mT时不同频率下的铁损变化.研究结果表明:随着扫描速度的降低,即激光体积能量密度的增加,合金样品的孔隙率降低,显微硬度升高,但是过高的能量密度也使得热应力增加而产生微裂纹,晶粒尺寸也较大;合金样品的主相均为γ-(Fe-Ni)相,微观组织主要为沿打印方向的柱状晶组织,但在其熔池边界附近也存在少量的等轴晶,晶粒大小呈现微观不均匀性;选择适合的能量密度对合金的内部质量及性能至关重要,在使用较适合的体积能量密度制备的SLM合金样品的相对孔隙率低于0.5%、矫顽力为270 A/m、饱和磁感应强度为1.2 T、剩余饱和磁感应强度为0.4 T;当磁场强度为10 mT时,随着频率从10 kHz增加至100 kHz,铁损随着频率的升高而升高. | 高硕洪 卢冰文 NOUREDINE Fenineche LIAO Hanlin | 2021 | 材料研究与应用2021，15，4： | 2 |
