Sažetak
ABSTRACT Production of 2XXX aluminum alloys solid sections is related with several mutually connected metal forming and thermal treatment processes. Experience accumulated in extrusion plant through the years of the production of these sections usually results with databases. These databases offer possibilities to relate sections properties with process parameters. This paper describes the procedure for analysis of mechanical properties of 2011 bars in both T3 and T8 tempers. For these purpose, a number of extrusion processes on horizontal 50 MN extrusion press were analyzed. Depending on the bar dimensions, the solid dies having one, two or more hordeles were employed. After extrusion, all bars were cold drawn with various reductions. All bars were thermally treated to appropriate temper. In this way, a database was established. An artificial neural network (ANN) model has been developed to relate mechanical properties to bar dimensions and cold drawing reduction for both tempers. After the ANN training and testing, an analysis was conducted in order to show how the mechanical properties of extruded bars depend on the particular aforementioned parameters. Optimization was conducted for the purpose of finding the optimal value of cold drawing reduction for achieving the best mechanical properties. Result of these investigations can be useful for industrial practice.
