High-strength steel checkup

By Gerald Ondrey |

Researchers from the Fraunhofer Institute for Nondestructive Testing (IZFP; Saarbrücken, Germany; www.izfp.fraunhofer.de) have developed the so-called Magnus hybrid — an inspection system that combines micromagnetic and ultrasound techniques to characterize materials. The micromagnetic method helps determine hardness, tensile strength and internal stress, whereas the ultrasound testing provides information about the texture of the material. The device is especially useful for examining high-strength steels used in lightweight construction materials.
