Influence of the Plastic Deformation on Magnetic Properties of Austenitic Steels

摘要

Austenitic stainless biomaterials are worldwide used in biomedical practice. Electromagnetic nondestructive evaluation allows their contactless investigation in terms of magnetic field mapping. Intrinsic magnetic field directly reflects changes in their mechanical properties. This article presents investigation of concrete austenitic biomaterials by use of fluxgate sensor. Pre-defined plastic deformation levels of the cylindrical specimens are evaluated. Three-dimensional scanning procedure has been performed.
