Since the bulk properties such as mechanical and functional properties of polycrystalline materials are strongly affected by microstructure, the control and optimization of the microstructure are essential to obtain desirable properties and to develop high performance polycrystalline materials. The application of external fields such as stress, electric and magnetic fields have been noticed as ...

Magnetic abrasive finishing can be classified as a non-traditional super finishing method for finishing surfaces with different shapes and working materials like flat plates, shafts, bearings parts, screws, tubes and many other mechanical parts that need good surface finishing properties. MAF is effective in polishing, cleaning, deburring and burnishing metal parts. The most important parameter...

This review deals with the definition and development of hard magnetic materials with special emphasis on more recent developments in this field. After discussing the fundamental properties of all hard magnetic materials, based on the intrinsic and extrinsic properties, some remarks on the history of hard magnetic materials and permanent magnets are given. The important hard ferrites are only b...

Magnetic materials are the key components of many electronics devices for storage and retrieval of information, such as computer hard drives and video tapes. Magnetic materials are also in high demand in power generation, non-polluting electric vehicles, medical science, telecommunication, etc. Due to wide technological applications of magnetic materials, there have always been quests for new m...

Recently, the phase-field method has been extended and utilized across many fields of materials science. Since this method can incorporate, systematically, the effect of the coherency induced by lattice mismatch and the applied stress as well as the external electrical and magnetic fields, it has been applied to many material processes including solidification, solid-state phase transformations...

ÐDevelopments in the ®eld of magnetic materials which show promise for future applications are reviewed. In particular recent work in nanocrystalline materials is reviewed, with either soft or hard behavior as well as advances in the magnetic materials used for magnetic recording. The role of microstructure on the extrinsic magnetic properties of the materials is stressed and it is emphasized h...

Magnetic materials, both hard and soft, are used extensively in several components of particle accelerators. Magnetically soft iron–nickel alloys are used as shields for the vacuum chambers of accelerator injection and extraction septa; Fe-based material is widely employed for cores of accelerator and experiment magnets; soft spinel ferrites are used in collimators to damp trapped modes; innova...
