Effects of Friction Stir Processing Parameters and In Situ Passes on Microstructure and Tensile Properties of Al-Si-Mg Casting

Influence of Multi-pass Friction Stir Processing on Microstructure and Mechanical Properties of Die Cast Al–7Si–3Cu Aluminum Alloy

“…Therefore, the globular Al-Si eutectic structure as the barrier may change the path of the dislocation movement, and therefore, FSPed material displayed superior tensile properties than the cast alloy. Cui et al [17] reported that the two-pass FSP sample exhibited an obvious advantage in the microstructure modification and the tensile properties compared with the one-pass sample.…”

“…They found from tensile test results that there is a good agreement between UTS and the hardness value as well as the particle size, where the UTS increases with increasing hardness and reducing the particle size. Cui et al [17] investigated the effect of FSP parameters and in situ passes on the microstructure and the tensile properties of Al-Si-Mg casting. They concluded that for the multi-pass FSP, the two-pass FSP sample exhibited an obvious advantage in the microstructure modification and the tensile properties compared with the one-pass sample.…”

Effect of friction stir processing conditions on fatigue behavior and texture development in A356-T6 cast aluminum alloy

“…It is known that FSW and FSP would reduce the hardness of T6-treated Al alloys after processing because of the resolution of hardening precipitates due to the heat input [11,12,17,18]. Thus post heat treatment was applied to the samples after FSP.…”

“…In a friction stir processing (FSP) technique, a rotating tool is plunged into a bulk plate just for the microstructural modification induced by severe plastic deformation. FSP had been applied to some cast Al alloys, revealing that casting defects were successfully eliminated by the severe plastic deformation [9][10][11][12].…”

Effect of Cooling Conditions on Mechanical and Microstructural Behaviours of Friction Stir Processed AZ31B Mg Alloy

“…FSP basically involves the same concept as Friction Stir Welding (FSW) which is a solid state processing technique for microstructural modification and improvement of mechanical properties [2] [3]. In FSP, a non-consumable rotating tool with a shoulder and a pin is embedded in the work piece and traversed along the desired path for localized microstructural variation for specific property improvement in the handled zone, arising from deep plastic deformation, blending and thermal presentation of the metal cooling in manufacturing processes which is known to improve a tool life and surface finish [4] [5].…”
