The Fraunhofer Institute for Nondestructive Testing IZFP carries out research and development activities in the field of nondestructive testing processes along the entire materials value chain. For customers in the automobile, aerospace, rail, energy, construction and agriculture industries, the institute offers a wide range of NDT expertise and technologies. At the 19th World Conference on Non-Destructive Testing, our researchers will be presenting a nondestructive micromagnetic materials characterization method by means of a variant of 3MA approach - the so-called 3MA-X8.
Iron and steel parts, as well as components used in machines, vehicles and plant engineering are often made of ferromagnetic materials. These components are heat-treated and machined in order to create the desired functional characteristics.
Determination of the quality of the surface layer properties requires suitable inspection methods. Micromagnetic methods offer a fast and nondestructive way to characterize and analyze materials properties during or directly after a production step with up to 100 percent process integration.
3MA is an acronym for "micromagnetic multiparameter, microstructure and stress analysis". The 3MA measuring systems of Fraunhofer IZFP determine, in fractions of a second, different material properties, e.g. hardness, case hardening depth.
In addition, a variety of other magnetic parameters is determined which reflect different material properties and stress states. The 3MA method determines the relationship between the magnetic characteristics measured and desired result parameters (e.g. hardness, case depth, tensile strength, yield strength, residual stresses) on the basis of a defined calibration sample set.
This is done using mathematical-statistical tools such as pattern recognition and regression analysis. Finally, an application of the calibration in order to inspect the calibrated component, finished and semi-finished product types is possible.
The 3MA-X8 measuring system implements the 3MA approach with particular emphasis on the possibility of a simple calibration, very high measuring speed and variable sensor design. In addition, simultaneous operation of up to eight sensors is possible with a device to cover several measuring positions or accelerate surface scans.
The application potential of this 3MA variant is discussed in this contribution regarding different application examples, and a comparison with the original 3MA approach is provided.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
