“…The precipitates that evolve during the SPD process are coarse in nature and hence do not contribute much to the enhancement in mechanical properties. Also, the dynamic precipitation depletes the solute concentration in the solid solution [18], which restricts the use of post process aging to produce nano precipitates. Post process solution treatment can be used to dissolve the dynamically emerged precipitates back into the matrix and then the sample can be peak aged to obtain a higher strength.…”

“…Due to the presence of non-deformable and brittle eutectics or primary silicon phase, the hot workability of the AlSi alloys is rather limited [8]. There have been studies [9][10][11] that focused on hot deformation of Al-Si alloys with near-eutectic or hypereutectic compositions. Ding et al [9] reported a good combination of tensile strength and elongation for hot extrusion of the Al-12Si-0.2Mg (wt.%) alloy.…”

Ding et al [9] reported a good combination of tensile strength and elongation for hot extrusion of the Al-12Si-0.2Mg (wt.%) alloy. Other studies [10,11] reported the hot deformability of hypereutectic Al-Si alloys at different strain rates and temperatures with a conclusion that to prevent coarsening of the eutectic silicon, the spray-formed hypereutectic Al-Si alloy should be hot extruded below 500°C.…”

“…The hot spinning process produces a high density of dislocations which are high stored energy zones around coarse eutectic Si particles. These energy zones with high stored energy supply preferred recrystallization nucleation sites and hence recrystallization occures [23][24][25] . …”

T he increasing demand for weight reduction in the automotive industry has resulted in a large research interest in aluminum alloys currently. A356 aluminum alloy is a kind of desired and commonly used material in the automotive field, such as suspension components and automotive wheels [1][2][3][4][5][6][7] . However, A356 products manufactured by casting process generally consist of primary dendrite with non-uniform solute distribution and defects, such as Fe-rich phases and porosities, which may lead to the reduction of service life [8] . Plastic deformation process is definitely an alternative to ameliorate some of the above negative aspects of cast alloys [9,10] . Casting-spinning technique is a kind of incremental forming technique employed on circular or tubular cast workpieces [11] . During the spinning process, a large amount of plastic deformation occurred. In recent years, the casting-spinning technique has been used in manufacturing automobile hubs. It has been validated that the application of this process is powerful to fulfill Abstract: The evolution of microstructure and mechanical properties of A356 aluminum alloy subjected to hot spinning process has been investigated. The results indicated that the deformation process homogenized microstructure and improved mechanical properties of the A356 aluminum alloy. During the hot spinning process, eutectic Si particles and Fe-rich phases were fragmented, and porosities were eliminated. In addition, recrystallization of Al matrix and precipitation of AlSiTi phases occurred. The mechanical property testing results indicated that there was a significant increase of ductility and a decrease of average microhardness in deformed alloy over die-cast alloy. This is attributed to uniform distribution of finer spherical eutectic Si particles, the elimination of casting defects and to the recrystallized finer grain structure.
