Since the end of 2004, periodic experimental investigations of the influence of strong magnetic fields on the corrosion of EUROFER steel-97 in Pb17Li flow have been carried out in the non-isothermal lead-lithium setup at the Institute of Physics, University of Latvia. Five experimental sessions have been performed of total duration 9,250 hours. In all experiments the EUROFER steel samples were located in the high-temperature part of the loop in a zone exposed to a uniform magnetic field (B = 1.8 T) and in a zone without the field. The experiments were carried out for different melt flow velocities Vmean = 2.5 cm/sec and 5 cm/sec, and different temperatures of the flow in the test-section Tnom = 515 C and 550 C. The minimum temperature of the flow in the loop was Tmin = 350 C. We report the results of gravimetric measurements of weight loss in the samples experiencing corrosion. Besides, pictures of the samples experiencing corrosion (after being washed in pure lithium) are enclosed. The obtained experimental results have confirmed the considerable influence of the magnetic field on the corrosion processes. The magnetic field, in general, not only intensifies the corrosion; it leads also to the formation of wave-like structures (grooves) on the Hartman surfaces, which are oriented in the melt flow direction.
