AbstractThe mechanical properties of extruded aluminium alloys behave differently as temperature rises. Accurate prediction of the mechanical properties of aluminium alloys at elevated temperatures is necessary for determining the load-carrying capacity of structures under fire conditions. This study focuses on the effects of high strength aluminium alloy 6061-T6 at elevated temperatures. The melting point of aluminium alloy 6061-T6 is found to be approximately 650°C. Therefore, tensile coupon tests were conducted at different temperatures ranging from approximately 24 to 600 °C for both steady and transient state tests. The material properties of aluminium alloy 6061-T6 with plate thickness of 4.5 mm were obtained. The tests were performed using servo-controlled hydraulic testing machine equipped with MTS 653 furnace. The Young's modulus, the yield strength (i.e. the 0.2% proof stress) and the ultimate strength versus different temperatures are also plotted and compared with the predictions from the American Aluminum Design Manual and Eurocode EN1999-1-2. The comparisons of the results are plotted and summarized in this paper, together with a detailed discussion. It is found that both the American Aluminum Design Manual and Eurocode generally provide conservative predictions for the high strength aluminium alloys at elevated temperatures.
