Abstract

In this work five different methods – AC magnetometer, DC magnetometer, Feritscope, EBSD and X-ray diffraction - were compared with each other. These methods were used to determine the δ-ferrite content of samples. The limits, disadvantages and advantages of the applied methods were analyzed. The tested material was 2507 type super-duplex stainless steel. The samples were cold rolled and heat treated to modify their ferrite content.

Keywords: ferrite content, alternating current magnetometer, direct current magnetometer, Feritscope, EBSD, X-ray diffraction
