“…The yield strength was determined to be 398 MPa from the 0.2% offset method, and the modulus of elasticity was derived to be 78.6 GPa. The mechanical testing results for this material are comparable to that of rolled, tempered Al 6061 [8].…”

This paper details the failure analysis of a wheel hub from a student designed Formula SAE Ò race car that fractured at the roots of the rim finger attachment region. The wheel hub was identified to be manufactured from a rolled Al 6061 alloy. The experimental characterization included fracture surface analysis and microstructural analysis using scanning electron microscopy, as well as compressive stress-strain testing and micro-hardness testing to determine its mechanical properties. Analysis of the fractured surfaces of the hub revealed beach marks and striations, suggesting a fatigue failure. A kinematic model was developed to determine wheel hub loadings as defined by the car driving history. Detailed loads calculated from a kinematic equilibrium model and material properties obtained from the experiment results were used in a finite element model to simulate the stress distribution and fatigue life of the wheel hub. The wheel simulation results were consistent with the failure mode determined from the fractography study.

“…Therefore, multiple studies have focused on SPD of these alloys [7][8][9][10][11][12][13][14][15][16][17][18][19]. However, the majority of these studies have considered Al-Mg-Si alloys in simple geometries (i.e.…”

“…Recently, a new SPD process called Tube Channel Pressing (TCP) has been developed to process tubular geometries [9][10]. Since precipitation hardening can be activated during the annealing treatment of Al-Mg-Si alloys [7,[12][13][14][15], the combination of TCP and post annealing of these alloys can be a good solution for development of tubes bearing an excellent strength and a good ductility. On the other hand, a few studies concentrated on the evolution of mechanical properties during annealing/aging treatments after SPD processes suggest that the effects of these treatments are strongly dependent on the imposed strain by SPD [15,20].…”

An Al-Mg-Si-Cu-Fe alloy was solid-solution treated at 560°C for 3 h and then cooled by water quenching or furnace cooling. The alloy samples which underwent cooling by these two methods were rolled at different temperatures. The microstructure and mechanical properties of the rolled alloys were investigated by optical microscopy, scanning electron microscopy, transmission electron microscopy, X-ray diffraction analysis, and tensile testing. For the water-quenched alloys, the peak tensile strength and elongation occurred at a rolling temperature of 180°C. For the furnace-cooled alloys, the tensile strength decreased initially, until the rolling temperature of 420°C, and then increased; the elongation increased consistently with increasing rolling temperature. The effects of grain boundary hardening and dislocation hardening on the mechanical properties of these rolled alloys decreased with increases in rolling temperature. The mechanical properties of the 180°C rolling water-quenched alloy were also improved by the presence of β″ phase. Above 420°C, the effect of solid-solution hardening on the mechanical properties of the rolled alloys increased with increases in rolling temperature.
