Fatigue behavior of 6xxx aluminum alloy processed by severe plastic deformation
Abstract
The 6xxx series aluminum alloys are widely used in the industry because of the combination of good mechanical properties and low density, exhibited of good corrosion resistance in many service environments and possess relatively good formability. In this study low-cycle fatigue tests were performed in ultrafine-grained (UFG) Al-Mg-Si alloy processed by hydrostatic extrusion (HE). This process can be classified as a severe plastic deformation (SPD) method and their advantage is possibility to obtain large amount of the material with a finely divided microstructure. The HE process was carried out on samples after solution treatment at 530°C during 1 hour with water quenching. As a result of the deformation, two degrees of total deformation (with value 1.8 and 4.6) were obtained, then samples were subjected to aging treatments. The fatigue tests were undertaken in the strain control with constant strain rate of 2B10-3 s-1, using standard round specimens. The cyclic stress–strain curves were determined using one specimen for each imposed strain level. The low-cycle fatigue results are used for the characterization of the cyclic plastic response and the fatigue live of the alloy. A comparison was made between the UFG state subjected to the HE process after two types of aging treatment, and the coarse-grained (CG) state of the material. The microstructure studies were performed using transmission electron microscope (TEM). It was shown that HE process leads to formation of the strong defected UFG microstructure with an average grain size of about 300 nm. The primary precipitates (AlFeSi and Mg2Si) and β'' phase creating after aging treatment were observed. The fatigue fracture surfaces were observed using a scanning electron microscope (SEM). The area of fatigue crack initiation in the material was located on the surface of specimens. The presence of typical area of stable crack growth and unstable crack growth with ductile fracture surface have been demonstrated. The results obtained in the fatigue tests of CG material demonstrated cyclic hardening at each strain amplitudes. The UFG samples after natural ageing showed cyclic softening at the beginning and then cyclic hardening up to break off, whereas for deformed samples after aging treatment the slight long term cyclic softening were observed.
