Abstract: The study of the deformation behaviour of the collector bar at conditions experienced within the aluminium reduction cell is of great importance to optimizing the efficiency and increasing the life span of the cell. This mémoire communicates the results of an experimental program carried out on the steel collector bar material (AISI 1006) to investigate its behaviour in relation to its thermal, mechanical and the creep properties. Tests were carried out in compression at low stresses, 0.5 to 2 MPa and high temperature, 900 °C. Different behaviour was observed at low stresses up to 2 MPa, which can be characterised by time and applied stress level. Metallographic inspection showed effect of oxidation and corrosion on tested samples due to the aggressive environment of the test condition, major efforts and modification were made to eradicate this effect and to improve the accuracy of obtained creep test data.
