Detection of carburization and defective weld in austenitic stainless steel using magneto-impedance arrayed sensor
Source abstract
Abstract
The present investigation addresses an electromagnetic sensor comprising of an array of rapidly quenched amorphous microwires. Given the arrayed configuration, along with its low field sensitivity, the sensor has a promising scope because of its larger footprint for the assessment of industrial steel components. The research involves a novel approach to the design of an arrayed magneto-impedance sensor with such attributes. The low sensitivity of a single microwire towards feeble magnetic field was enhanced through a multi-wired arrayed magneto-impedance (MI) sensor. The arrayed microwire sensor output has been enhanced through Joule annealing of amorphous microwires. The potential scope of arrayed MI sensors for the detection of carburization in austenitic stainless steel and defective welds has been demonstrated. The low field sensitivity has been endorsed through COMSOL Multiphysics simulation studies.
