Research scientists from the Fraunhofer Institute for Nondestructive Testing IZFP in Saarbrücken, Germany, have developed the MAGNUS hybrid inspection system to investigate the material properties of high strength steel before they are processed.
High-strength steels are in demand as lightweight construction materials. If machines, cars and other devices are to become as energy efficient as possible, they need to become progressively lighter.
The speciality about this MAGNUS system is that it combines micromagnetic and ultrasound techniques to characterize materials.
“While the micromagnetic method helps us to determine properties such as hardness, tensile strength and internal stress, the ultrasound testing informs us about the texture of the material, a critical factor governing the material’s deformation characteristics during the deep drawing process,” explains Fraunhofer IZFP research scientist Dr. Klaus Szielasko, who is leading the MAGNUS project.
The MAGNUS project brings together scientists from Fraunhofer IZFP and their colleagues at the Technical Centre for Mechanical Industry CETIM in Senlis, one of the network of Carnot institutes. Together they have developed a tool that allows micromagnetic and ultrasound techniques to be employed alongside one another to characterize materials.
“We placed particular emphasis on coming up with a cost-effective tool and sensor concept,” stresses Szielasko.
Within the scope of industrial contracts, three systems for heavy plate inspection were already manufactured based on MAGNUS technology. The scientists will be showcase their hybrid inspection system at the EuroBLECH trade fair.
