Abstract: A magnetorheological fluid formulation exhibiting consistently high yield stress during use. The MR fluid comprises martensitic or ferritic stainless steel particles prepared by a controlled water or inert gas atomization process. The stainless steel particles are resistant to corrosion and oxidation, are generally smooth and spherical, and maintain their shape and size distribution throughout their use under an applied magnetic field.
