MagStar: A Portable Magnetic Hysteresis and Barkhausen Emissions based Electromagnetic Device for Non-Destructive Evaluation of Steel Structure/Component

Manufacture of  Portable Magnetic Hysteresis and Barkhausen Emissions based Electromagnetic Device

The developed NDE device can be used for evaluation of microstructural changes during heat-treatment/ agenig, detremination of ferrite volume fraction, evaluation of ferromagnetic phases and its correlation with mechanical properties and residual stress analysis.

• The developed magnetic NDE device is suitable to use on-site to assess the extent of damage accumulation in components after extended period of service at high temperature.
• The developed magnetic NDE device is able detect the extent of creep and fatigue damage that is experienced by steel component.
• The device is suitable to evaluate carburisation depth at the inner surface of the process heater tube used in petrochemical industry.
• The device is suitable to detect the damage of initially non-magnetic process heater tube wherein magnetisation appears at the inner surface due to carburisation during in-service operation in petrochemical industry.
• The device is suitable to detect the presence of magnetic phase in non magnetic-materials.
