The Magnetic Field

Functionally graded materials are attracting more attentions because of the continuously varying properties in different locations. How to design and fabricate FGMs has become a key and difficult point. In this paper, a magnetic-field-driving method is developed to prepare Ni/epoxy resin FGMs by moving a narrow magnetic field from one end of the sample to the other end with the moving direction perpendicular to the field direction. Ni follows the moving of the magnetic field, and a gradient distribution is obtained. The composition gradients are influenced by Ni content, moving velocity, and also cycle times. The results illustrate that this magnetic-field-driving method is an effective way to prepare FGMs, which is very promising into scientific and technological applications.

The Magnetic Field

This paper describes technology, which can be used to obtain ceramic-metal composites with a gradient of metal particles concentration. Graded composites, have been obtained by slip casting. The gradient of iron concentration was induced by magnetic field. Microstructures of the specimens have been investigated using a light and scanning electron microscopy. Quantitative analysis of microstructures has been carried out with the help of image analyzer. The obtained results prove the possibility to produce Al2O3-Fe functionally graded materials under the magnetic field.

AbstractThe aim of this contribution was to investigate the microstructure of in situ Al-Si functionally graded materials produced by traveling magnetic field. The research shows that the composition and associated microstructural feature of Al-Si alloys processed by this method changes from the outer of samples to the inner, respectively, from Al-Si hypereutectic with particles of primary Si to Al-Si eutectic to hypoeutectic composition with a great number of primary Al dendrites. Moreover, the hardness, the wear resistance of samples and the volume fraction of primary Si particles all have obviously gradient characteristics in the samples.
