Applications
Many manufacturing processes involve some modification of stress and/or microstructure that can be readily analyzed with Barkhausen noise. For example:
Machining — grinding, turning, milling
Cold working — shot peening, laser peening, autofrettage
Surface hardening — carburizing, nitriding, induction hardening
Various dynamic processes such as creep and fatigue similarly involve changes in stress and microstructure and can also be monitored with Barkhausen noise.
