MagStar
A Portable Magnetic Sensing Device for Non-destructive Evaluation of Steel structures and components
Overview
MagStar is a Magnetic NDE device developed jointly by M/s Technofour, Pune and CSIR-National Metallurgical Laboratory, Jamshedpur. It measures Magnetic Hysteresis Loop (MHL) and Magnetic Barkhausen Emissions (MBE) using a single magnetizing probe. It has also the option for measuring MHL and MBE separately. The device is portable and light weight.
Applications
- Evaluation of microstructural
changes during heat-treatment/ageing - Determination of ferrite volume fraction
- Evaluation of ferromagnetic phases and its correlation with mechanical properties (e.g. hardness)
- Residual stress analysis
Features
- Magnetic Hysteresis Loop and Magnetic Barkhausen Emission in a single probe
