“…As these previously ECAPed processed parts have a lower value of wear, a lower loss of volume [21][22][23][24] is obtained in the parts. In addition, a great deal of attention has been paid to the wear resistance of copper [25][26][27] and copper alloys [28] processed by severe plastic deformation processes.…”

Abstract:Over the last few years there has been an increasing interest in the study and development of processes that make it possible to obtain ultra-fine grained materials. Although there exists a large number of published works related to the improvement of the mechanical properties in these materials, there are only a few studies that analyse their in-service behaviour (fatigue and wear). In order to bridge the gap, in this present work, the fatigue and wear results obtained for connecting rods manufactured by using two different aluminium alloys (AA5754 and AA5083) previously deformed by severe plastic deformation (SPD), using Equal Channel Angular Pressing (ECAP), in order to obtain the ultrafine grain size in the processed materials are shown. For both aluminium alloys, two initial states were studied: annealed and ECAPed. The connecting rods were manufactured from the previously processed materials by using isothermal forging. Fatigue and wear experiments were carried out in order to characterize the in-service behaviour of the components. A comparative study of the results was made for both initial states of the materials. Furthermore, Finite Element Modelling (FEM) simulations were used in order to compare experimental results with those obtained from simulations. In addition, dimensional wear coefficients were found for each of the aluminium alloys and initial deformation states. This research work aims to progress the knowledge of the behaviour of components manufactured from ultrafine grain materials.

This work aims to investigate the temperature rise in Aluminum alloy 6061 due to deformation heating in equal channel angular pressing (ECAP) and high-pressure torsion (HPT) processes using finite element method. The roles of various parameters are investigated and the heating of ECAP die due to billet deformation is included in the simulations. The results show that while the work-piece moves in the exit channel, the generated heat is transferred to die via conduction and therefore the temperature isosurfaces in die are extended in the direction of inlet and exit channels. The dependency of maximum work-piece temperature to velocity is more than its dependency to friction. Increasing the plunger velocity increases the difference between maximum and minimum temperatures. Additionally, the maximum work-piece temperature is attained at the deformation zone. The temperature rise in HPT is less than ECAP due to the small size of the HPT work-piece compared to ECAP. Not only the work-piece size, but also the good heat conduction of aluminum makes the temperature distribution roughly uniform in HPT.

“…There are plenty of studies about SPD processing of Al-Mg-Si alloys, such as ECAP [27][28][29] or high pressure torsion (HPT). [30][31][32] However, the main emphasis is placed on the combination of grain boundaries strengthening with an age hardening [27,33] or optimizing mechanical and electrical properties by applying aging process.…”

In this study, an Al-Mg-Si alloy was processed using via incremental equal channel angular pressing (I-ECAP) in order to obtain homogenous, ultrafine-grained plates with low anisotropy of the mechanical properties. This was the first attempt to process an Al-Mg-Si alloy using this technique. Samples in the form of 3 mm-thick square plates were subjected to I-ECAP with the 90 deg rotation around the axis normal to the surface of the plate between passes. Samples were investigated first in their initial state, then after a single pass of I-ECAP, and finally after four such passes. Analyses of the microstructure and mechanical properties demonstrated that the I-ECAP method can be successfully applied in Al-Mg-Si alloys. The average grain size decreased from 15 to 19 lm in the initial state to below 1 lm after four I-ECAP passes. The fraction of high-angle grain boundaries in the sample subjected to four I-ECAP passes lay within 53 to 57 pct depending on the examined plane. The mechanism of grain refinement in Al-Mg-Si alloy was found to be distinctly different from that in pure aluminum with the grain rotation being more prominent than the grain subdivision, which was attributed to lower stacking fault energy and the reduced mobility of dislocations in the alloy. The ultimate tensile strength increased more than twice, whereas the yield strength was more than threefold. Additionally, the plates processed by I-ECAP exhibited low anisotropy of mechanical properties (in plane and across the thickness) in comparison to other SPD processing methods, which makes them attractive for further processing and applications.
