Toward Magnetorheological Finishing of Magnetic Materials
Journal of Manufacturing Science and Engineering, 2007Magnetorheological finishing (MRF) is a precision optical finishing process traditionally limited to processing only nonmagnetic materials, e.g., optical glasses, ceramics, polymers, and metals. Here we demonstrate that MRF can be used for material removal from magnetic material surfaces.

Magnetic Plasticine™: a versatile magnetorheological material
Journal of Materials Chemistry, 2012A novel black Plasticine™ was developed by dispersing iron microparticles into the paraffin wax–petroleum jelly composite matrix. Due to the presence of magnetic particles, this Plasticine™ exhibited magnetic-dependent mechanical properties and can be defined as a typical magnetorheological gel (MRG) material.

Smart Materials Based on Magnetorheological Composites
Materials Science Forum, 2012Magnetorheological elastomer composites (MREs) based on different magnetoactive fillers such as: carbonyl iron powder (CIP), gamma iron oxide (γ-Fe2O3), micro-and nanosize Fe3O4 are reported and studied. MREs were obtained from various elastomer matrixes such as: ethylene propylene, acrylonitrile butadiene, silicone, ethylene-octene and polyoctenamer ...

Magnetorheological Finishing of Tungsten Carbide Mold Materials
International Optical Design Conference and Optical Fabrication and Testing, 2010Recent MRF polishing results of Tungsten Carbide (WC) mold materials will be presented. Excellent roughness values are reported, particularly on fine-grained TSJ02 WC, which led to sub-nanometer Ra values.

Selection of Materials in Designing Magnetorheological Brake
Applied Mechanics and Materials, 2014The braking system is among the most significant active safety systems in a vehicle application for preventing injuries and property damage. Whether for light or heavy vehicles, brakes are no longer a small issue whereas it becomes a crucial problem to maintain the safety and to avoid the unpredictable cases especially on the road.

MAGNETORHEOLOGICAL MATERIALS BASED ON IRON ALLOY PARTICLES
International Journal of Modern Physics B, 1996A magnetorheological material containing iron alloy particles demonstrates magnetorheological strength dependent upon the elements of the alloy and relative concentration of the alloy elements. Selected iron/cobalt alloys demonstrate improved yield strength over traditional carbonyl iron based MR materials when the iron-cobalt alloy has an iron-cobalt

Research on Material Removal of Magnetorheological Finishing
Key Engineering Materials, 2007Magnetorheological finishing (MRF) is a novel precision optical machining technology. Owing to its flexible finishing process, MRF can eliminate subsurface damage, smooth rms micro roughness and correct surface figure errors. The finishing process can be easily controlled by a computer. Material removal model in MRF is established. According to Preston

Research on Material Removal Mechanism of Magnetorheological Finishing
Materials Science Forum, 2006Magnetorheological finishing (MRF) is a novel precision optical machining technology. MRF utilizes magnetic particles, nonmagnetic polishing abrasives in carrier fluid, and a magnetic field to finish optical materials. Owing to its flexible finishing process, MRF eliminates subsurface damage, corrects surface figure errors and the finishing process can
