Magnetization and Stress Effects in Steel

Stress has long been known to be one of the major factors affecting the magnetic behaviour of ferromagnetic materials. It therefore influences magnetic inspection techniques for steel. It has also been proposed that magnetic measurements can be used to monitor stress [1]. We are particularly concerned with magnetic inspection techniques for pipelines [2]. We investigate stress effects by two complementary approaches, namely by experimental studies of magnetic flux leakage signals using laboratory test rigs to reproduce the behaviour of magnetic inspection tools used for pipelines and by studies of the magnetic behaviour of representative steel specimens under tensile and compressive strains.
