Abstract
This paper presents the results of experimental tests of monotonic tension and torsion, creep-rupture and preliminary creep at 200 °C and 300 °C, as well as low-cycle fatigue of 2024T3511 aluminum alloy. The fatigue process was conducted at room temperature for uniaxial tension/compression and torsion. The as-received material and pre-deformed material were also investigated during creep at elevated temperature. Basic monotonic, creep and fatigue characteristics of the material were determined. Detailed micro- and macroscopic analyses of fracture surfaces (scanning electron microscopy, SEM) were carried out. The influence of different creep pre-deformation histories at elevated temperature on the behavior of the studied alloy were characterized with respect to monotonic and cyclic loads at room temperature.
