Phase Transformations in Austenitic Steels and Their Monitoring through Barkhausen Noise

/in , /by

The lecture presents research in the field of Barkhausen noise in austenitic steels, where martensite is formed through deformation processes. This phase transformation is also associated with the transition from a paramagnetic phase to a ferromagnetic one. Regarding plastic deformation, processes such as simple tension, dynamic strengthening of materials, rolling, friction, as well as long-term combined loading of a ship propeller are presented. The presentation highlights the importance of exchange interaction between individual martensitic regions, as well as the dominant influence of the amount of deformation-induced martensite on Barkhausen noise.

Anisotropic deformation of spin systems

/in , /by

The task of the seminar will be to illustrate the modern methods of analysis of magnetic materials using the so -called. Tenzor networks. Three basic types of phase transitions (first, second and endless order) will be elaborated in detail and illustrated in a simple model with anisotropic spin interaction. This model has been designed to offer new perspectives of theoretical justification of experimental measurements of magnetic materials.
