Barkhausen Noise Analysis

Non-destructive (NDT) measurement solutions for grinding burn and heat treatment defect testing

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.
