In this application, gear teeth were checked for grinding re-temper burn after a gearbox manufacturer uncovered a failed tooth.

In this application Barkhausen noise testing measures the ferro-magnetic steel substrate through the coating on landing gear piston.

In this application camshaft lobes were inspected for soft spots (heat treatment defect) with non-destructive barkhausen noise method.

In this application, gear teeth were checked for grinding burn as a result of unbalanced cycle time changes.

In this application, camshaft lobe was checked for microstructural defects. These invisible non-uniform changes in the microstructure can ultimately lead to cracking at a later time.

In this application, the grinding of a crankshaft journal was checked for unfavorable stresses due to overheating during grinding, also known as grinding burn.

MBN is quantitative, repeatable, non-destructive, and it is easily automated, thus removing operator influence as a variable.

Residual stress is one physical property that is becoming more crucial as the requirements and quality of manufacturing process grow.

Cold working causes plastic deformation that creates residual stresses.

Residual stresses are spontaneously in equilibrium as tensile residual stresses (detrimental) and compressive residual stresses (beneficial).
