چکیده
Aluminium foams possess multi-functional properties and a low specific weight, making them one of the most suitable choices in application domain automobile aviation sectors, vibrating machining, structural parts. Compared to traditional fabrication routes, friction stir processing (FSP) is gaining acceptance as it cost-effective, highly efficient, innocuous process fabricate foam precursors from bulk substrate. In current study, FSP was utilized develop precursor with MgCO3 powder acting blowing agent. The experiments were performed per Taguchi’s L8 orthogonal array. heat treated an electric furnace at holding temperature 650 °C for 10 min. After post-heat treatments, this resulted porous structure due evolution CO2 gas composite. simultaneous effect tool rotation speed, traverse shoulder diameter investigated on pore size porosity produced. composite parameter “unit stirring” found be closely related processed zone (PZ) volume rate zone, size, degree porosity. highest 16.67% obtained average 10.5 µm. largest 17.8 µm, observed associated 14.40%. analysis Kiviat plot revealed that values PZ area polar symmetry unit stirring. density both symmetrically distributed about

The Strength of Friction Stir Welded and Friction Stir Processed Aluminium Alloys
Local strength of friction stir (FS) welds and FS processed aluminium alloys in heat treatable aluminium alloys is dominated by precipitation hardening. Strengthening due to stored dislocations is generally limited to 40MPa, and grain size strengthening is generally less than 10MPa. Local crystallographic texture can cause yield strength variation on the order of 5%. Published models for streng...
متن کاملFriction stir welding and processing
Friction stir welding (FSW) is a relatively new solid-state joining process. This joining technique is energy efficient, environment friendly, and versatile. In particular, it can be used to join high-strength aerospace aluminum alloys and other metallic alloys that are hard to weld by conventional fusion welding. FSW is considered to be the most significant development in metal joining in a de...
متن کاملOn the fabrication and characterization of Al5083/Al2O3 surface nanocomposite via friction stir processing
In the present study, Al5083- Al2O3 nanocomposite was successfully prepared by friction stir processing (FSP) with rotational speed of 710 rpm and travel speed of 14 mm/min. In order to improve distribution of Al2O3 particles, a net of holes were designed on the surface of Al5083 sheet. The samples were characterized by optical and scanning electron microscopy (SEM), microhardness, tensile and ...
متن کاملFatigue of Friction Stir Welded 2024-T351 Aluminium Alloy
Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld. Fatigue failure from the surrounding material was essentially conventional, initiating from large S-phase intermetallic particles and growing in a macroscopic mode I manner. ...
