We reinforced aluminium matrix composites with three different amounts of red mud. These red mud reinforcements were manufactured using stir casting and then subjected to ECAP for evaluating the structural and wear behaviour. The formation of submicron size grains significantly enhanced the hardness, which in turn significantly lowered the loss of wear for ECAPed composites. A reduction in the wear rate was noticed with the rise in the percentage of RM reinforcement. Before ECAP, the least wear impact noted was in the composite that had 10 weight percent reinforcement. After ECAP, the least wear rate was found in the composite that had 15 weight percent reinforcement. The wear rate might have been minimized because of the elimination of the oxide layers after ECAP. At higher loads, the frictional thrust increases, consequently increasing the de-bonding and detaching of the material. Therefore, a rise in normal load raised the wear rate.

“…Since these methods of plastic deformation were demonstrated as an efficient approach to produce ultrafine-grained (UFG) or nanostructured (NS) materials about two decades ago [17] [18], many investigations have been carried out to examine SPD techniques and to find out which processing parameters is most important and to establish most efficient deformation routes for manufacturing UFG metals and alloys with enhanced mechanical properties. So far, among all SPD techniques, equal channel angular pressing (ECAP), or called equal channel angular extrusion (ECAE) [19] [20], has attracted the most attention. This method is one of the most effective in producing UFG structures and can be used for producing UFG billets large enough for various structural and industrial applications.…”

In this study, commercial Al-3%Mg aluminium alloy was subjected to ECAP processing using two different ECAP die configurations. The first one – conventional and the second one modified in which a part of the exit channel in the ECAP die, causes twist deformation, to impose extra shear strains to the sample. The local changes in microstructure were characterized by Light Microscopy, SEM equipped with an EBSD facility and TEM. Mechanical properties of the ECAP processed samples were compared based on hardness measurement. The results showed that when ECAP with modified die, the greater grain and crystalline refinement is possible. The microstructures exhibit high dislocation density within subgrains with non-equilibrium and Moiré boundaries. Moreover, the mechanical examinations display a significant improvement in hardness and calculated yield strength when the ECAP process is conducted using a modified die.
