Abstract
The correct performance of heat treatments and machining processes is important for the functional behavoir and fatigue strength of stressed components. The only methods in use for an evaluation of surface quality are techniques like metallographic inspection, X-ray diffraction, strength and hardness tests. They can however not be integrated into the production process because their testing speed is too slow and because most of them are destructive in nature. Nondestructive techniques which can be integrated into the production line are now available. Combining the complementary information obtained through vaious micromagnetic parameters the 3MA testing unit allow a fast evaluation of quality characteristics of hardened parts and components.
