Recrystallization microstructure in cold-rolled aluminum composites reinforced by silicon carbide whiskers

Influence of TiO2 particles on recrystallization kinetics of Al–2Mg–TiO2 composites

“…These differences in thermal properties play significant role to alter the kinetics of various metallurgical phenomena, such as recover, recrystallization, etc., during annealing treatment. The generation of greater number of dislocations in particulate reinforced AMCs (Al-SiC, Al-Al 2 O 3 ) owing to their thermal mismatch is known to significantly affect recrystallization kinetics of composites [6][7][8][9][10][11].…”

Studying Some of Mechanical and Thermal Properties of Al-SiC composites

“…These materials are characterized by the ability to combine many different characteristics through composing between two materials or more which have different characteristics, those are called composite materials [1,2]. These materials are characterized by high resistance to temperatures under different ambient conditions, in addition to good mechanical properties like having high strength, toughness and stiffness, besides light weight with low density and resistance to corrosion which suit usage fields in advanced applications like spaceships, satellites, electronics, aircrafts, cars and many military applications [3,4]. The composite materials result from binding between two phases, the first is the Matrix Phase, and the second is the Reinforcement Phase.…”

Effects of Solution Atoms and Precipitates on Isochronal Annealing Behavior of Cold-Rolled Squeeze-Cast SiCw/Al Composites

“…During such forming operations, AMCs may experience an appreciable amount of cold working, which may both influence their further forming operations and degrade mechanical properties, such as elongation to failure and fatigue resistance. Therefore, after forming operations it may be necessary to anneal the composites to recover their deformation ability and mechanical properties [7,[11][12][13][14][15][16][17][18]. To optimize forming operations and mechanical properties of AMCs, understanding the annealing behavior of plastically deformed AMCs is essential.…”

“…These studies focus mostly on AMCs manufactured by powder metallurgy route, including particulateand whisker-reinforced composites, in which fine dispersions of Al 2 O 3 is present. It was reported that, for powder metallurgy Al-SiCw composites, the reinforcing whiskers were of a significant influence on the deformation and recrystallization behavior of the matrix alloy [11][12][13][14]. Firstly, when whisker volume fraction was equal to or less than 8%, the presence of whiskers resulted in a more inhomogeneous deformed microstructure in the matrix of AMCs compared with those unreinforced materials.…”

“…pct SiCw didn't show recrystallization behavior may be due in part to the role of fine dispersions of Al 2 O 3 . In order to both eliminate effects of solution atoms and precipitates existing in matrix and make a direct comparison between reinforced and unreinforced materials, research on recrystallization has been carried out on a range of MMCs with commercially pure aluminum as the matrix [11,13,14]. However, MMCs with pure aluminum as matrix are rarely used in engineering applications; therefore it is necessary to investigate the recrystallization of MMCs with aluminum alloys as matrix from the point of view of engineering applications.…”
