TL;DR: In this paper, the structural, magnetic and mechanical properties of co-based magnetic microwires and their composites were investigated and it was found that annealing amorphous microwires at 600 C caused a drastic variation in the amorphized structure due to crystallization and consequently degraded the soft magnetic properties of the microwires.

NDT techniques for railroad wheel and gauge corner inspection
TL;DR: In this paper, the development of non-destructive techniques (NDT) techniques for the in-service inspection of railroad wheels and gauge corners was the main activity of the NDT division VIII. 4 at BAM over the last 2 years.
Ndt techniques for railroad wheel and gauge corner inspection
TL;DR: In this article, two fundamentally different inspection techniques were chosen in order to satisfy the end-user requirements: rim and disk inspection without dismantling the wheels and using ultrasonic techniques, and inspection of the railway track surface at a train speed of about 70 km/h using eddy current techniques.
High-Speed, High-Resolution Magnetic Flux Leakage Inspection of Large Flat Surfaces
TL;DR: In this article, a new approach to magnetic flux leakage (MFL) testing of flat surfaces which reaches high speed and high local resolution with a small amount of sensors and implicitly compensates for different sensor properties during the measurement is discussed.
The MFL technique for surface flaws of weld zone with residual magnetization method
TL;DR: In this article, the three components of the residual lea kage magnetic fields from the flaws were measured with the MI sensor and finite-time analysis for the residual magnetic fields was carried out.
