Microstructures and wear property of friction stir welded AZ91 Mg/SiC particle reinforced composite

Microstructure and texture evolution during accumulative roll bonding of aluminium alloy AA5086

“…A significant fraction (∼50%) of grains have diameter <100 nm while the average lies within 150-200 nm. [31][32][33][34][35] 3.3. Texture evolution…”

“…Consequently this component strengthens in the bulk texture. Cube oriented grains, on the other hand, nucleate at transition bands or can result from a preferred growth relationship (38• around <111>) with the S-component [30,32]. Subsequently, the cube component forms by the rotation of copper oriented grains towards the fiber presentinthe deformedmaterial.…”

Microstructure and mechanical properties of friction stir welded dissimilar Mg alloys of ZK60–AZ31

“…However, the application of Mg alloys as complicated part has been limited because of their poor workability. To widen the applications, it is important to consider the welding properties of Mg alloys [3,4]. So far, several methods have been studied for joining Mg alloys, which include TIG, MIG, laser beam welding and friction stir welding (FSW) [5][6][7].…”

Particle Size Effects of Silicon Carbide on Wear Behavior of SiCp-Reinforced Magnesium Matrix Composites

“…SPD of the original material leads to reduction of the molecular component of the friction coefficient. Lee et al [13] investigated the microstructures and wear property of friction stir welded (FSW) AZ91 Mg alloy/SiC particle reinforced composite (AZ91/SiC/10p). The initial microstructures of the AZ91/SiC/10p were composed of irregularly distributed b-phases (Al 12 Mg 17 ) and agglomerated SiC particles, while the friction stir weld zone was characterized by the homogeneous distribution of SiC particles, the recrystallized grain structure and the dissolution of b-phase.…”

“…Previous studies mainly focused on the increase of the wear resistance of the matrix alloy by incorporation of SiC particles, both for Al MMCs [5,6] and Mg MMCs [4,[7][8][9][10][11][12][13][14]. The research focused on how the size of silicon carbide particles affects the wear behavior of SiC p -reinforced AZ91 Mg MMCs was inadequate.…”
