Role of Friction Stir Channel Geometry on the Fatigue Behaviour of AA5083-H111 at 120°C and 200°C Catarina Vidal1, a and Virgínia Infante2,b * 1, 2ICEMS – Institute of Materials and Surfaces Science and Engineering, Instituto Superior Técnico, Technical University of Lisbon, Av.
The fracture of all specimens took place in the nugget/TMAZ interface on the advancing side (AS).
All specimens have fractured at the advancing side, in the nugget/TMAZ interface which is an abrupt transition zone of very fine to coarse grain.

High nitrogen austenitic stainless steel is a kind of advanced resource-saving materials which can effectively save large amounts of nickel, and their strength, hardness, wear resistant and corrosion resistance are much higher than the traditional austenitic stainless steels due to the positive effects of nitrogen [1, 2].
Therefore, high nitrogen austenitic stainless steel has broad application prospects in the energy, construction, transportation, nuclear engineering, ocean engineering and medical surgical industry, and their research and development has also become one of the focuses in the current international new materials fields.
