TA Instruments introduces an all new system for characterization of magneto-rheological (MR) fluids. The Magneto-Rheology Accessory for the Discovery Hybrid Rheometer enables parallel plate and cone-plate rheological measurements under the influence of a controlled field at temperatures as high as 170 °C and fields as high as 1 T.

MR fluids are one class of “smart fluids,” those fluids that can have their flow properties change greatly and reversibly by the application of an external stimulus, such as a magnetic field. These advanced materials have current and potential applications in fields such as advanced automotive bearings and suspensions, tunable polishing slurries, and ballistic defense.

The MR Accessory from TA Instruments can be used in conjunction with a Discovery Hybrid Rheometer for complete rheological characterization of these materials under controlled temperature, deformation, and magnetic field up to 1 Tesla. This provides substantial benefit to scientists developing and optimizing MR fluids and the devices that use them.

RheometryRheometers are used to measure the rheology of fluids, which is the flow of fluids in response to an applied force. The most common types of rheometer include shear rheometers (capillary, cone and plate and rotational cylinder) and extensional rheometers. Viscometers are similar to rheometers however viscometers only measure the viscosity of a fluid.Non-Destructive TechniquesNon-destructive techniques (NDT) describes a variety of analytical techniques used to evaluate the properties of a material. Common methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), and eddy-current testing. NDT is regularly used in forensic engineering, civil engineering, mechanical engineering, electrical engineering, systems engineering, aeronautical engineering, and medicine.RheologyTemperature ControlTemperature controlled processes are experiments carried out using ovens, furnaces, incubators, hotplates, refrigeration and freezers.Pressure ControlSmart Materials
